Combine like terms
8u+3u= 11u
and
9v-5v= 4v
So the answer is 11u+4v
356/8 = 44.5
44.5 miles per hour, miles/hour
Lets plug in the answer choices and see which one works
A. x = -6
| -6 | < 3
6 < 3
False, so A is not the answer
B. x = -5
| -5 | < 3
5 < 3
False, so B isn't the answer
C. x = -1
| -1 | < 3
1 < 3
True, so C is the answer.
But lets just check D to make sure C is the answer.
D. x = 2
| 2 | < 3
2 < 3
False, so D isn't the answer either.
C is your answer :)
The answer is x= -17
hope this helps
