In a football game, a running back ran for -7 and -5 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? a)78-5-7 b)78-5+5 c)78+5-7 d)78+5+7

D:78+5+7

Step-by-step explanation:

We are given that in a football game , a running back ran for -7 and -5 yards on his two runs.

His total yardage for the whole game=78 yards

We have to find that which expression shows how many yards the running back had before those two runs.

Total yardage=78 yards

Sum of two runs=-7-5

Now, number of yards had before  two runs is given by

Hence, the expression which shows number of yards the running back had before two given runs

D:

D:78+5+7

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5
