Choose the equation that represents this situation. Use wto represent the
variable.

does he spend in the weight room each week?
A.3w=4
B. w=3•4
C.3+w=4
D.4w=3

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

  measure of length.   there are 12 inches in a foot, and 36 inches in a yard.   one inch is exactly 2.54 centimeters.
