The answer that I got was -66. You would subtract 71 by 9. Then you add 4. The answer is negative because there is an odd number of negatives.

Answer:

Carla has been running 7 miles each day for 13 days.

Step-by-step explanation:

Carla ran 3 miles on her first day, 5 miles on her second day and then 7 miles each day onward.

Let the number of days she ran 7 miles each day = x

Total distance run by Carla = 3 + 5 + 7(x)

= 8 + 7x

If her log book shows that she has run total distance = 99 miles

Equation representing her total run will be,

8 + 7x = 99

7x = 99 - 8

7x = 91

x = $\frac{91}{7}$

x = 13 days

Therefore, Carla has been running 7 miles each day for 13 days.
