How did you do #6? I don't understand how you got 6k out of 3(1-2k). I thought when you cleaned up both side it would look like -2k=3(-1k)....how did you get 6k?

thank you sooo much!!

thanks

Great video..... Helped a lot

thank you soooo much i love you god bless,, i have a test tommorow about this and i know ima do great thanks again

You have no idea how much you helped me! Thank you so much!!!

great video, it helped me out a lot

Thank you , very helpful.

Thank you a million times,you really helped me with my test!

Sure.

Could you do a video on the second question of mixture. Thank you so much, you're the best.

Yes! I was in a rush - thanks for pointing it out! Mr. D.

You're correct, thanks.

Thanks, I appreciate it!

hydroCHLORIC acid would not burn through concrete. you are probably thinking of hydroFLOURIC acid.

The 12 problems that are posted on my website. The ones at the end of the video was homework from last Thursday.

Do we do the problems from the textbook, the six problems from the video, or both?

Never mind!

For the sixth problem, how did you get from 6/5 to 4/5?

Sorry for the late reply, but you don't have to take notes just do the 4 example problems (pause button problems) and the 4 at the end of the video.

The sub was really mean in our period.

Should we be taking notes?

Jack so desparate in seeing FPS games.

Wait..what? There are people who dislike math????

where's number 6?

Clearing the fraction is a very useful technique to make many problems much easier. but it is not the only way to do problems with fraction. The way you did #3 is perfectly fine and just as easy as clearing the fraction. I'm glad that you have the skill to do a problem more than one way - way to go!

On problem 3, out of habit I subtracted the 5 and multiplied by -2, instead of clearing the fraction. I still got the same answer, but should I clear the fraction instead?

Thanks!

The perimeter is 44. Remember, you add all the sides of the rectangle (i.e., W+W+L+L) to get the perimeter.

in #3 it says two less than twice the width do you mean two times less than twice the width or two meters less than twice the width?

YAY I'm learning!!!!!!!!! :D

No. The other two problems are on the video (#3 and4) at the end. Just pause and write them down.

2 example problems (please go through the steps with the video) and 2 problems I want you to try on your own. We'll be going over several problems in class tomorrow.

....when you give it a hard work-out, it hurts. (I'm not a great typist)

Your brain is like a muscle - when you give it a hard work-it out, it hurts. The more you work out a muscle, the bigger and stronger it gets; just like your brain.

remember that the perimeter is 44, so you need to define your variable (one of the sides) and find the relationship to the other side and go from there. We'll be working this out in class tomorrow. #4 also.

Not until next week.

No, you don't have to draw a diagram - but it's a good habit to get into as the problems get harder.

hey mr. devor! for number 3 i can not figure it out! i have tried just about everything, but obviously i havent. lol. what should the equation be to start the problem?

Yes, just the 4. I'll be checking - and going over - #3 and 4.

whens the test?

i thought there was 6 problems

is there just 4 problems?

repeat after me: I Loooooove word problems, I Looooove word problems.......

i Have ps3 :D

You want to get the absolute value bars alone. In #4 it was 4 times the Abs Value expression - so you needed to divide to get the abs val alone. In #5, it was the abs value minus 3, so you need to add 3 to get the abs value alone. Good question - I'll do a couple of examples in class tomorrow.

quick question--how do you know when to divide (problem 4) versus adding/subtracting (problem 5)

yes. do the 6 example problems (i.e. pause...try the problem...un-pause and check your answer) in a box 6 format.
