Question

Oliver runs for 9 more minutes than Bobby.

The equation v = 9 + b, where v represents the number of minutes Oliver runs, and b represents the number of minutes Bobby runs, shows this relationship.

If Oliver runs 33 minutes, how many minutes does Bobby run?
A. 15
B. 42
C. 24
D. 51

Answer 1

The answer is C 24 if you plug in 33 33 = 9 + b you have to subtract the 9 over to 33 to get 24

Answer 2

C. 24

If Oliver runs 9 minutes more, and we already know how long he ran, then we need to do the opposite of the equation, which is to subtract instead of add. 33-9=24
