Multiple Choice

Solve -2 = 4r + s for s.

• s = -2 + 4r
• s = 2 - 4r
• s = -2 - 4r
• s = 2 + 4r

Multiple Choice

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a 

Multiple Choice

Solve for y:
5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16

Multiple Choice

Solve for n:
2m - n = 8

• n = 2m - 8
• n = -2m - 8
• n = 2m + 8
• n = -2m + 8

Multiple Choice

Solve for x:

• x = yb - v

Multiple Choice

Solving the formula P = 2L + 2W for W is not equivalent to which equation?

• (P-2L)/2 = W
• (P/2) - (2L/2) = W
• (1/2)P - L = W
• P - (1/2)L = W

Multiple Choice

pV = nRT
solve for R

• R= pV/nT
