Answer:
29 miles per gallon
Step-by-step explanation:
Take the miles and divide by the gallons
435/15
29 miles per gallon
There is a problem with this question.
if 15 students is 92% of the class, the total class size is therefore
N=15*(100/92) = 16.3, or 16 students (to the nearest integer).
So far so good.
However, if we check back, 15 students out of 16 is 15/16*100%=93.75%, nowhere near 92%. I have no idea where the 92% came from, and hence I doubt if there might not be a typo, by the submitting user, or the teacher.

5x - 7y =58
y =-x +2
Using the substitution method, replace y in the first equation with the second equation:
5x - 7(-x+2) = 58
Simplify by using the distribution property:
5x - (-7x) - 14 = 58
Simplify by combining like terms:
12x -14 = 58
Add 14 from each side of the equation:
12x = 72
Divide both sides by 12:
X = 72/12
x = 6
Now you have x, replace x in the second equation and solve for y:
y = -x +2
y = -6 +2
y = -4
X = 6, y = -4
