Today we did practices of DPE, MPE, SPE, and APE.
Our POD was the following: 1. x÷8-4=5 and 2. 8÷x-4=5
For question number one we used APE to change x÷8-4=5 into x÷8=9 (adding 4 to each side) Then we used MPE to change x÷8=9 into x=72 (multiply 8 to both sides)
For question number two we used APE first to change 8÷x-4=5 into 8÷x=9 (adding 4 to both sides) then we used MPE to change 8÷x=9 into 8=9x (multiplying both sides by x) then we used DPE to change 8=9x into x=8 over 9 (fraction)
Then we solved a story problem that Luanna made yesterday.
The story is the following:
Margo had 5 rings. Lilly gave her some more. Then Austin gave her twice as many as Lilly gave her. Margo, deservedly or not =] ended up with 26 rings.
To answer the problem we made it into an equation. 26=5+x+2x.(x=number of rings Lilly gave Margo.)
We combined Like Terms. Which gave us 26=5+3x. Then we subtracted 5 from 26, 5 and 3x. Which gave us 21=3x. Then we divided both sides by 3. Which gave us 7x. Then we had to multiply the answer by 2, because Austin gave Margo twice as many rings. Which gives us the final answer. 14 rings.
HOMEWORK: Finish worksheet Mr. A gave us in class today.
