Answer:
(C)90 – 10y = 5x
Step-by-step explanation:
Given:
x = number of times she hiked the 5-mile trail
- Then, total Distance covered on the 5-mile trail =5x
y = number of times she hiked the 10-mile trail
- Then, total Distance covered on the 10-mile trail =10y
Maria hikes a total of 90 miles
Therefore, total distance hiked can be represented by the equation:
5x+10y=90
Subtract 10y from both sides, we have:
5x=90-10y
This is option C.
360 - 4x - (x+40) - (x+10) = A
A = 360 - 4x - x - 40 - x - 10
A = 310 - 6x
A = 142
