2x+7 = 3x - 7
3x - 2x = 14
x = 14
2x + 7 + 12y + 1 = 180
2(14) + 12y + 8 = 180
28 + 12y + 8 = 180
12y + 36 = 180
12y = 144
y = 12
answer
C. x = 14 and y = 12 (third choice)
Set up a proportion:
First convert 75 inches to feet.
75 in = 6.25 ft
1/6.25 = x/50
Multiply 50 to both sides:
50 * 1/6.25 = x
50/6.25 = x
x = 8
So the tire will rotate 8 times after Frank rides 50 feet.
