Question

During a 4th of July weekend, 32 vehicles became trapped on the Sunshine Skyway Bridge while it was being repaved. A recent city ordinance decreed that only cars with 4 wheels and trucks with six wheels could be on the bridge at any given time. If there were 148 tires that needed to be replaced to due to damage, how many cars and trucks were involved in the incident?

Answer 1

x=cars
y= trucks

Answer 2

32 cars so x=y+32

Answer 3

car has 4 wheels so 4x and tucks have 6 wheels so 6x

Answer 4

total number of wheels is 148 so 4x+6y=148

Answer 5

x+y=32
4x+6y=148
so the answer is 148

Answer 6

Answer 9

mulptly the equation by-4 to get rid of x and then solve for y

Answer 10

Answer 11

-4x-4y=-128
4x+6y=148

2y=20
y=10

10 trucks and 22 cars where involved
