1. solve for p

3 (p+q) = p

A. q=-2/3p

B. q=-3/2p

C. p=-2/3q

D. p=-3/2q

2. solve for b then find the value of b when a=3

4a=2b-7

A.-9/2

B. 5/2

C. 19/2

D. 17

3. solve for r

d=rt

A. r=dt

B. r=t/d

C. d/t

D. r=d-t

4. find the width of a rectangle with a perimeter of 90 and a lenth of 15.

A. 90

B. 15

C. 45

D. 30

1. solve for p3 (p+q) = p

D. p=-3/2q

2. solve for b then find the value of b when a=3

4a=2b-7

C. 19/2

3. solve for r

d=rt

C. r = d/t

4. find the width of a rectangle with a perimeter of 90 and a lenth of 15.

D. 30

1.

To solve for P = p3 (p + q) = p

We combine the P's together p - p3 - p = q

The p = 3/2q.

The correct answer is D.

2.

To solve for b when the value of a = 3

4a = 2b - 7

we put 3 where there is a

(4 * 3) = 2b - 7

12 = 2b - 7

19 = 2b

b = 19/2

The correct answer is C.

3. To solve for r

d = rt.

In order to get r, we divide both sides by t

d/t = rt/t

r = d/t

The correct answer is C.

4. The width of a rectangle with a given perimeter of 90 and length is 15.

The perimeter is the whole rectangle.

We are given length is 15.

To find width which is one side it should be,

90/15 = 30

Width is 30.

The correct answer is D.
