$10.55 , because he has $5.55 left after he bought the movie ticket . If the snack was only $5 , then he wouldn't need to borrow any money . So B would be wrong . You add the $5 dollars he owes the friend to the money he already has and you get $10.55
Sub in -7 as x
-(-7)^2 + 8(-7)
= -49 -56
= -105
Answer:
Step-by-step explanation:
The diameter of a tire is the distance across the tire through the center. Since tires are circular, you can find the circumference of the tire from the diameter. The circumference represents the distance the tire travels when it makes one revolution. If you know the number of inches in a mile and the circumference, you can find the number of times the wheel turns per mile.
First, measure the diameter of the tire in inches.
Secondly, multiply the diameter by pi, which is approximately 3.1416, to find the tire circumference. For example, if the tire has a 20 inch diameter, multiply 20 by 3.1416 to get 62.83 inches.
Answer:
x= 5y where y is no of revolutions and x is the distance traveled
Step-by-step explanation:
Let y be no. of revolutions and x be the distance traveled so the equation will be
x=5y
when y= 1 x=5 ft
when y=2 x=10 ft
when y=3 x=15 ft
when y=4 x= 20 ft
when y=8, x=40 ft
