I hope you weren't just guessing.
1.
3p + 3q = p
2p = -3q
p = -3q/2
The way you typed the answers, none are valid
2.
d = rt
d/t = r , all you have to do is divide both sides by t
3.
2L + 2W = P
30 + 2W = 90
2W = 60
W = 30
0 for 3 , looks like somebody has some work ahead
Solve for p
3 (p + q) = p
A. q = -2/3 = p***
B. q = -3/2 = p
C. p = -2/3 = q
D. p = -3/2 = q
Solve for r
d = rt
A. r = dt***
B. r = t/d
C. d/t
D. r = d - t
