Answer:
The correct answer is a) 16
Step-by-step explanation:
To find this first distribute the interior negative to both terms in the parenthesis.
9 - {x - (7 + x)}
9 - {x - 7 - x}
Now simplify the like terms.
9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.
16
x – slower car
3x faster car
D = distance traveled by slower car
D = distance traveled by faster car
D+d = 129
Both cars traveled for 2 hours
D=2x
d=2(3x) = 6x
2x+6x = 129
8x = 129
x=129/8 = 16.125 miles per hour
