The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Please show all work. A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

the circumference is 5, since the diameter is half, so you have to double 2.5 to get 5.    2.5 + 2.5 = 5

if the tire rotates 1 time and gains 5 feet, we have to divide 5 from 5,280. So...

5,280 ÷ 5 = 1056

it rotates 1056 times to get to 1 mile!

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
