Question

In a football game, a running back ran for 5 and 7 yards on his last two runs. His total yardage for the whole game is 78 yards. Which expression shows how many yards the running back had before those two runs?\

PLEASE HELP I REALLY NEED THE ANSWER

Answer 1

Forgot, the choices are:
A. 78 – 5 – 7
B. 78 – 5 + 7
C. 78 + 5 – 7
D. 78 + 5 + 7

Answer 2

my answer is b. is this correct?

Answer 3

B is not correct.

78 – 5 + 7 = 80

Answer 4

The answer is A. Because the total amount of yards AFTER he ran 5 and 7 yards is 78, but they ask what expression show how many yards the running back had BEFORE the two runs so the answer is A. Because you have to subtract 5 and 7 from the end score to figure out what he had BEFORE the last two runs.

Answer 5

11\left[\frac{\left(9^{2}-5\right)}{2^{2}+8}\right]
