A=21 B=125 C=34
A= C-13
B=4C-11
A+B+C=180 (all angles of a triangle add to 180)
(C-13)+(4C-11)+C=180
6C-24=180
6C=204
C=34
34-13=21=A
4×34-11=125=B

Answer:
A+ Rental charges $0.60 per mile.
Rock Bottom Rental charges $70 plus $0.25 per mile.
Let 'x' be the number of miles driven. Let 'y' be the cost of the rental.
The equation for A+ Rental:
y = $0.60x
The equation for Rock Bottom Rental:
y = $0.25x + $70

Answer:
2
Step-by-step explanation:
7 ( 2 e - 1 ) - 3 = 6 + 6 e
Expand brackets
14 e - 7 - 3 = 6 + 6 e
Simplify
14 e - 10 = 6 + 6 e
Minus 6 e from both sides
8 e - 10 = 6
Add 10 on both sides
8 e = 16
Divide by 8 from both sides
e = 2
