Remember C = pi * d (pi = 22/7 and d is the diameter which is 8400)
Substitute 22/7 and 8400 into the equation
C = 22/7 * 8400
C = 22 * 1200
C = 26400 miles
Answer:
hi BS
22
Step-by-step explanation:
nickels 15. dimes 15
7 more means
15+7 giving us 22
By dividing the price per gallon, we see that for every gallon he pays three dollars.
18 Dollars/ 6 Gallons=3 and 21 Dollars/7 Gallons= 3.
So for 8 Gallons, if he pays that same rate of 3 Dollars, he will pay $24.

12x^3 +2x^2-30x = 8
2x( 6x^2 +x -15) = 8
so 2x= 8, x=4
(2x) ( 2x-3) ( 3x+5) = 8
2x-3 = 8
2x= 11
x= 5.5
3x+5=8
3x= 3
x=1
