Step-by-step explanation:
Without a calculator, you can cross multiply
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.
Answer:
35
Step-by-step explanation:
x+8+243/2
x+251/2
x+251/2=4x+3
cross multiply
x+251=2(4x+3)
x+251=8x+6
x-8x=6-251
-7x=-245
x=-245/-7
x=35
