At the gym, Diana always spends 12 more minutes running then lifting weights.
Which equations describe the relationship between the number of minutes Diana runs, r ,and the number of minutes she lifts weights
A. 12 + w = r
B. r = w - 12
C. w = 12 + r
D. r - 12 = w
E. r + w = 12
EVALUATION
Here it is given that at the gym, Diana always spends 12 more minutes running then lifting weights.
Now
The number of minutes Diana runs = r
The number of minutes Diana lifts weights = w
Since Diana always spends 12 more minutes running then lifting weights
So r = w + 12
FINAL ANSWER
Hence the correct option is A. 12 + w = r
