So in class on February 3 we wrote a test on problem solving. Here are 4 of the questions of the test :

Today in class our assignment was to correct our tests that we had yesterday. Here are 5 of the questions that I had problems with.

9a+5-4a
*How to get the simplified answer:
9a+5-4a
9a-4a+5
5a+5
What I did was first I grouped like terms. I did 9a-4a and the answer I got to that question was 5a. Second I added a five to positive 5a. So when you do that your answer would be 5a+5.


3x+(4x+6)5
*How to get the simplified answer:
20x+30+3x
20x+3x+30
23x+30
The first thing I did to get the simplified answer was multiplied 5 by 4. When I did that I go 20x, then I multiplied 5 by 6.I got 30 when I did that. So I had 20x+30+3x. I added the like terms, which gave me,23x then I brought the 30 down. The simplified answer would be 23x+3o.


Six less then a number divided by 4 is 25
n-6/4 =25


Six less then triple a number is nine,
3n-6=9


the difference of a number and six times 4 is 32
6x4
n =32

The next scribe post will be done Erika Espaldon. (: <3>HAHA
