1) Solve for p.

3(p+q)=p

(1point)

Q=-2/3p

Q= -3/2/p

P= -2/3q***

P=-3/2q

2) Solve for b, then find the value of b when a=3.

4a=2b-7 (1point)

-9/2

5/2

19/2

17***

3) Solve for r.

D=rt (1point)

R=dt***

R=t/d

d/t

r=d-t

4) Find the width of a rectangle with a perimeter of 90 and a length of 15. (1point)

90

15

45***

30

Ok, Am I correct, I need to make sure to get these right because if I do, I get the rest of the day off… not that you might care but still.

1.

3p+3q = p

2p = -3q

p = -3q/2 , which is the last one, not yours

You just have to mind your p's and q's

2. 4a = 2b-7

4a+7 = 2b

b=(4a+7)/2 = (12+7)/2 = 19/2

3. D = rt

r = D/t

4. totally wrong!!!!

Your choice of answer is totally illogical, just think about it.

If the width is 45, then the two widths together would be 90.

But the whole perimeter is already 90

You missed All of them!!!

Wow, looks like you don't get the rest of the day off, and you have lots of studying to do
