<span>suppose the speed = x mi/h
Overspeed cost = 115 + x - 65 = 50 + x ....... 1
Overspeed Cost = 50 + (x -65)*10 = 10x - 600 ..........2
from [1] and [2], we get,
10x - 600 = 50 + x
10x -x = 50 +600
9x = 650
x = 72.22 mi/h
hope it helps

Answer= 59.8mph
So since it takes 3h of 50mph to get from Ashdown to Bridgetown Carol drives for 150miles. Because 3*50 is 150.
Then divide 60 by 70 which is 0.857. Then times 0.857 by 60 to see how long it took her , which is 51 mins. Add 3h and 51mins which gets you 3.51h.
Then add 150 and 60 to get 210. Divide 210 by 3.51 then you get 59.8 mph
Answer:

Answer:
yes
Step-by-step explanation:
Substitute the point into the equation and see if it is true
x- 5y = 10
0 -5(-2) = 10
0 +10 = 10
10 = 10
This is true so the point is a solution to the equation
