1.) B
2.) C
3.) D
4.) can you rewrite the question?
Eva spent 2 hours tutoring and 6 hours clearing tables.
Let x represent the number of hours Eva worked tutoring and y represent the number of hours Eva worked clearing tables.
Eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Hence:
y = 3x
-3x + y = 0 (1)
16x + 8y = 80 (2)
Solving equations 1 and 2 simultaneously gives:
x = 2, y = 6
Eva spent 2 hours tutoring and 6 hours clearing tables.

5 because half of 20 is 10 so half of 10 is 5
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
