Set as equation of x
2x-5y=15
2x=15+5y
x=(15+5y)/2

set to 0
solve for y
0=(15+5y)/2
0=15+5y
-15=5y
-3 = y

It would be -3. Your equation would be. -5y=-2x+15. Then you divide everything buy -5 and come out with y=-2/-5-3.

Sue needs to drive 372 miles to visit her aunt. She stopped at a gas station one-third of the way in to her trip. How many miles

IRINA_888 [86]

Answer:

Sue has traveled 124 miles.

Step-by-step explanation:

Here, the distance covered by Sue is a fraction of the total distance to be covered.

The total distance to her aunt's = 372 miles

but the gas station is at one-third of the distance to be covered.

Thus,

Miles traveled by Sue = $\frac{1}{3}$ x 372

= 124

Miles traveled by Sue = 124 miles.

Therefore Sue has traveled 124 miles.
