ok sooooooo…i still have trouble with proofs unless they are partially filled out…:P anywayssssssss the question we had yesterday was this.
i was doing a proof and the thing said something like:
<AOB + <BOA = 90
so i said it was a congruent angel cause it equaled 90 degrees. but the answer key said that it was substitutive property. but wouldnt it be a congruent angle??
Hi…
Substitution is a way to have one thing take the place of another.
In Geometry an example would be:
<A + <B = <C
then you find out that <C = 90
so you can now use "substitution" to say that
<A + <B = 90
90 has been "substituted" for <C
Happy Proofing!
Mr. D
i found out why my answers were wrong on that test. In lesson 83 im watching the video to a problem and i was using the pythagorean thereom to answer a question and when we got to the end the guy didn’t find the root…it was x squared equals 48 and so i punched it in to find the square root and came up with a decimal…but he gave 16×3 as the answer then simplified it as 4 squared times 3. so that confuses me…cause of what u taught me.
ok so now it’s triangles and finding their angles. i cant figure it out…irritating. and the proofs (as well as the triangle proofs) are killing me…i can’t complete a whole lesson cause of it. so ya.
Colin
Think of Traingles like half of a rectanlge.
If a rectangle has 4 right angles – each 90 degrees, that is a total of 360, then a triangle (any triangle) will have a total measure of 180 degrees!
Mr. D
Hi Mr. D,
The math problems you gave us on the cd’s. How should i post them?
When it says to post to the Algebra course work discussion baord, post there, otherwise you will keep in your notebook for the next time the co-op meets.
Mr. D
Mr. D:
Are you aware that examples 1.4 both have errors.
Mr.D:
I do not understand the two questions in session 1.5:
Question 1–
If 18 / 2 = 9
then
10 x ___ = 9
Question 2–
If 50 / ___ = 25
then
10 x 1/2 = 25

Great super detective work…you found an error on the worksheet!
Hi Mr.D!
I was wondering if we were suppost to do all the questions on section 1.3.. or are those just for practice?
Thnks!
Bethany E.
All the questions miss Bethany…
Just write the answers on your own paper.
Mr. D
super! thanks!
The 1.7 Coursework I sheet says Order of Operations Four Steps (5). What does the 5 mean? Does it mean that we have to answer five questions? Or are we supposed to answer all 20 questions?
Thanks,
Jonathan
Hi Jonathan,
All 20…the 5 should not be there!
You are such a good detective
hi mr d.
My computer is being stubborn and isn’t letting me watch your math videos! Ive tried everything! what do i do??
Thanks!
Bethany E.
HEELLLPPP!!!!
i am having alot of trouble with section 1.5! i dont get it at all =( its so confusing!
Thanks
Bethany E.
Hi Mr. D
I’m kind of confused when you did examples on section 1.7 because on question 11 you did the 10 divided by 300 write out.. I looked at it and tried to figure it out but i don’t get how you did that..
Thanks!
Bethany E.
i figured it out so thanks anyways!
i watched the video again and found out what you were talking about =)\
Thanks!
Bethany E.
I got a question about test taking skills.. I got the video and stuff but on the HW what do i write for the pics with the pencils and books??
thanks
Bethany E.
i am confused on section 2.7 algebra.. i cant figure out how to do all the mixed up ones like c-12c-19an+19c.. i get all confused about how to do it..
( and im doing it right now because i lost my cd and i just found it 2day.. its my falt cuz i forgot to put it back in the case after i was done using it!)
Bethany E.
Hi Mr D.
I am having problems with your cd’s. I will have to send you directly to jail, do not pass Go, and do not collect $200.
Thanks,
Tiger W.
I thought when you divided -8 by -4 the answer stays negative but the calculater said positive 2! help ME!
hey micheala, when you multiply or divide two negatives you get a positive but if only one of the numbers is negative then the answer will be negative!
does that make sence to you??
Natalie
If the number of negative signs is odd, the answer will be negative but if they are even, the answer will be positive.
yea, that too!!
Natalie
Hey Mr.D!!
I’m finally better!! So I’m doing the test and I was wondering…. You say on the problems to show all steps and does that include checking our work??
<Bethany<
Yes…definitely check your work…that’s a great way to know if you have the question right or not!
Mr. D
Hey Mr.D..
I’m trying to watch section 2.7 and I did everything like I usually do and i clicked on the PC folder and it says that there is nothing in the folder.. =P I don’t know what to do!
Bethany E. =)
Hiya Mr. D, my brother and I tried to do 1.6 today, and we didn’t understand it at all! What should we do?!
Hi Mr. D.
Are we supposed to answer all 21 of the questions in part 1 of the lesson 2.1 course work? And if so, how? Do you want us to post our answers on here?
Hey Mr. D!
I just finished watching my math video for section 4.3 and it was about Graphing Linear Equations and I looked at the course work and its saying stuff like “How do you change a mixed number into a improper fraction?” and thats not what I learned in the video… I’M SO CONFUSED!!!
Thanks
Bethany E.
Hey Mr. D,
I barely understand anything.. I can’t get any of the course work right and I don’t understand how to use excell. I am so confused!!
The new Pre-Algebra Disk, Section 4 Number Theory, Fractions DOES NOT WORK. It is an unreadable disk and I cant access anything.
Mr. D
THIS IS URGENT. On coursework 4.9 ques. 18 I get 3x = -4 +-2y. Is the answer negative or positive???
Hi Mr. D
I totally forgot what homework do we have for this week! what is it again?
Thanks!!
-Bethany E.
Hey Mr.D,
I didn’t really get what I was supposed to do with
the PLACE VALUE chart. I need an overveiw to know what to do PLEASE!
Thanks,
Joshua B.
I need a reply as fast as you can because I’m trying
to finish my test today!
Thanks,
Joshua B.
hi what if the x2 looks like x to the second power
how do you tell the diffrence
Hi,
If it is a second power it will have a ^ in front of it.
Like 3^2 means 3 to the 2nd power.
Mr. D
Hiya Mr D. !
How do I do the course work for 4.1 Course Work part IV? I don’t understand how to find the Factor Family
Hi Mr.D
and I think you might have made a mistake on Part 1 question 8 pg. 1. The question is Convert 10111 in Base 2
I was checking my work for section 5.1
Base 5= (your answer)=23 (my answer)= 43
Base 10= (your answer)- 43 (my answer)- 23.
I double checked what it says on the chart and looked at your answers again and the chart says I’m right but your answer says I’m wrong.
HELP!!
< Bethany E. <
HELP!!!
Same thing just happened on question 9 Section 5.1 pg.2
The question was-
Convert 10010 in Base 2
Your answer was
Base 5= 18
Base 10= 33
My answer was
Base 5=33
Base 10=18
And I double checked the chart and the chart said I’m right but then I looked at your answer and your answer says its wrong =(
Help!!! I’m confused!!
< Bethany E. <
Hi Mr. D
You said on Section 5.2 to print out a place value chart for 5.2 and I don’t see one. Did you mean to print out the 5.1 chart?
Thanks!!
-Bethany E.
Hey Mr. D,
I’m confused about a problem in section 5.2 part 1 page 2….. When finding m, or slope, I use the y2-y1 over x2-x1! But sometimes u do y2-y1 over x1-x2! If I do that it will change my answer! What should I do?
Hey Mr.D
I lost my cd and I can’t find it! =( Could I possibly get another one?
Thanks!
-Bethany E.
Hey Mr. D,
I’ve lost my math CD and was wondering if you could email section 5.3 to me because thats all I have to do for Monday! =) Thanks!
Natalie
Hi Mr. D!!!
could you possibly email me the sections… Thanks!!!!!!!!
I lost my math cd!!!
<BETHANY<
Hey Mr. D!
I am still confused about the chapter 4 test. I don’t remember how to find slope the 3 different ways! I watched the video but I still don’t get it.
Hi Mr.D!!
I am confused on 5.8. Could you possibly give me some pointers? Thanks!!!!
-Bethany E.
Hi Mr.D
My CD doesn’t work. Could you send me the file for 6.4?
Thanks!
-Bethany
Hey, Mr. D! I got a new temporary computer, so could you please send me chapters 5.7 and 5.8 for Mac please?
Thanks!
Hey Mr. D
I did not get the chapter 11 test. So could you please send me the test??
Thanks
Hi Mr. D!
I’m kinda confused with the grade stuff.. Is it the sooner I do all my work for the week the better I get for the on time thing? Or should I do one section a day. If i stretch out my work so I start on like tuesday and end on friday does that mean my grade will lower? Or does it lower if I’m doing my work on saturday or sunday or I dont finish it at all.
Sorry if this was confusing!!!
Bethany E.
What do I need to do with the Grade Book again?
Put your grades in!
Let me know and I can help with it in class!
After the lecture, where do I go to get the course work problems? The DVD just goes into lecture 1.3.
Hi,
Did you find everything?
Mr. D
Hey Mr. D I need help with two answers in 1.2 the question said to subtact 87-48 and I did and I came out with 39 but the answer you came out with was 35 and my dad who is a math expert checked over it and said it was right and he said he does not know how you got that answer so I watch the video called a freind and I still can not figure it out so i really need help…………
Hi Mr. D!
My excel worksheet isn’t working right. I can’t put in my grades because there is no room. And it doesn’t look like the one you sent me in the email. I asked Taylor if he could figure it out and he tried and said that he couldn’t figure it out either.. HELP!!
Thanks,
Bethany E.
Hi Bethany another copy to you.
Let me know if that one works
Mr. D
Hey, I’m in the pre-algebra class and I was wondering what the homework from Wednesday was?
Hi,
1.4, 1.5, and 1.6
Mr. D
Hey Mr. D
Is there going to be a Geometry Corse work section on the website? Just wondring
not in chapter 1, but there will be some coming!
Hi Mr. D!
I just wanted to double check on the homework for this week. Is it
1.4
1.5
1.6
Thanks!
Bethany E.
Hi and now it is 1.7 and 1.8
Hey Mr.D I was not there monday because I was sick (and still am) so for 1.8 is it the same thing as 1.7 because I already did that if it is the same??????????
Mr D.,
I do not understand how to make up a pemdas problem with the answer being zero.
Kaley G. Pre-Algebra class
Hi there Kaley,
Here is the best way to do it…
start with 0 and work up to the beginning.
0
10 – 10
2 * 5 – 8 + 2
2* (5 + 6 – 3 * 2) – 2^3 + 2(9 / 9)
Keep playing with it!
Ok, Thanks Mr.D!
Hey Mr. D!!
I’m trying to send my work for the pemdas and
it’s saying that I need to refresh my email so I
don’t know if I need to make a microsoft
email or if I can just use my own and I’m doing
something wrong.. Thanks!!
Hey Mr. D!
I am doing my 1.7 course work and I’m doing it with the video. And alot of the questions that your doing on the video are on my worksheets so is it ok that I did it step by step with the video? Like I would pause the video then write down my answers and then play the video and you would put down your answers and if mine were not right I would change them right there. Or do you want me to not watch the videos and do the coursework at the same time and just do my coursework with out doing it with the video since it gives me the answers. Sorry if this is confusing!!
-Bethany E.
That is the perfect to do the problems and use the videos!
Very smart!
Mr. D
Hey Mr. D!
Do you want me to post my all that work for nothing problem on the Algebra page or should I just show you in class?
Thanks!
Bethany E.
If you would post on the site, that would be great!
Remember no class tomorrow!
It’s labor day holiday
Test coming later today!
Ok. Sounds good!!
-Bethany E.
Hi Mr. D!!
As long as all my answers equal 0 then I did my work right for section 1.7? Because I was looking at how you did some and mine look a little different compared to yours with some numbers and when I added and multiplied and stuff.
Thanks!
Bethany E.
Yes – get them to equal 0 – checking with a calculator will have you know for sure if the way you did them worked!
Mr. D
Hey Mr. D!!
I was trying to check my work for section 2.1 and I didn’t find any answer keys for the number charts and the box thing where you put the name and then write certain numbers. So I was wondering where it went and if I’m maby just missing it on the computer.
Thanks!!
-Bethany E.
Hey Mr. D!!
I was trying to put in the dates that I got all my stuff done this week in the gradebook
and each time I put in like Sept-13 it puts in all these random numbers and wont give me my grade!
-Bethany E.
The answer 3.1 for question 4 says the answer is -24cm + 7c. This is wrong, it is -34cm + 7c.
For problem 14 in section 2.5 when I looked in the solutions it said that the answer was negative when in the multiplication there were an even number of negative signs…?
Hey Mr. D,
What are we suppost to do with course work 7.1 part 1?
It has the fill in the blanks but next to it it has lines to write on. Do we put in our answers for the blanks there or do we right the whole question? And there’s also ones where there isn’t any blanks. What do I do with those?
Thanks,
Bethany E.
Why does it matter whether the “x” is first in the translation of 8 less than a number is 24?
because 8 is not more than 24 so if you take anything away from 8 it would not end up as 24.
