Answer:
e = -2
Step-by-step explanation:
9e-7=7e-11
Subtract 7e from both sides
9e-7e -7=7e -7e-11
2e -7 = -11
Add 7 to each side
2e -7+7 = -11+7
2e = -4
Divide each side by 2
2e/2 = -4/2
e =-2
You have the following equation for the cost of renting a car for x number of miles driven:
y = 0.15x + 65
If you travel 70 miles, then, x = 70 and you obtain for the cost y:
y = 0.15(70) + 65
y = 10.5 + 65
y = 75.5
Hence, the cost of renting a car to drive 70 miles is $75.5
Answer:
3/2
Step-by-step explanation:
(3/4)/(1/2)=(3/4)(2/1)=6/4=3/2
220-220r=160
Solve for r to get the discount rate
r=0.2727
r=0.2727×100
r=27.27%
Check
220−220×0.2727
=160
