Homework Help: math (college algebra)

Posted by Sam on Thursday, September 2, 2010 at 6:01pm.

Ok I have two questions I have NO CLUE how to complete on my homework. Please help ASAP!

(1) Solve the formula for the specified variable

r = vx for r (the question is) v = ?

a = 1/3f * p for f (the question is) f = ?

(2) Solve the forulma for v

S = D + vm (the question is) v = ?

1. r = VX.
Divide both sides by X:
V = r/X.

a = (f/3)p
Multiply both sides by 3:
3a = fp,
Divide both sides by p:
f = 3a/p.

2. S = D + vm
Subtract D from both sides:
vm = S - D,
Divide both sides by m:
v = (S - D) / m
