C - 2c = 2c - 2c - 4
c - 2c = -4
-c = -4
c = 4

Answer:
![\Large \boxed{ -x+65}](https://tex.z-dn.net/?f=%5CLarge%20%5Cboxed%7B%20-x%2B65%7D)
Step-by-step explanation:
Two points are (0, 65) and (10, 55)
Calculate slope <em>m</em>
![\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![\displaystyle m=\frac{55-65}{10-0}=-1](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7B55-65%7D%7B10-0%7D%3D-1)
Use slope-intercept form
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
![y=-1x+b](https://tex.z-dn.net/?f=y%3D-1x%2Bb)
<em>b</em> is the y-intercept, y-intercept is (0,65)
![y=-1x+65](https://tex.z-dn.net/?f=y%3D-1x%2B65)
Thank you for posting your question here. Please see below answers for the problem above:
a. to find the circumference of the tire you need to multiply 3.14 by 2.5:
= 3.14 x 2.5
= 7.85 to round of it will be 8
b. to get the number of times the tire have to rotate to travel 1 mile:
1 mile = 5,280 ft
1 rotation is 7.85
5,280/7.85 = 672.611465
