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

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
