The answer is C
I pretty sure
Answer:
x=1
Step-by-step explanation:
This stuff is quite easy in reality. Here's a little example including your numbers.

by this point we are left with simplifying it. Since it's a double negative we get a positive. Thus x=1
X=3i,-3i ;) used calculator to check
Carla would have 4 laps left
Vincent ran 1.5 times faster than Carla
Carla is running half as slow as Vincent
So, the miles Carla would have covered would be half the miles covered by Vincent
Miles Carla would have covered when Vincente finishes his race =
8 / 2 = 4 laps

Number of laps remaining for Carla to run = 8 - 4 = 4 laps
