2.5 divided by 2 equals 1.25 so each side equals 1.25
3 and 32
Step-by-step explanation: 32 *3 equals 96
So we have the following system of equations:

We need to solve it by substitution. This means that we have to take the expression for x given by the second equation and replace x with it in the first equation:

So y=-1. If we use this value in the second equation:

So we have x=2 and y=-1 which means that there's one solution. Then the correct answer is A and the solution is (2,-1).
He uses 15 gallons. Because 270/6 = 45. Meaning he drives 45 miles per gallon. So 675/45=15. 15 gallons he will need to use to drive 675 miles.
