Answer:
162.4 miles
Step-by-step explanation:
We can write a ratio to solve
116 miles x miles
----------------- = ------------
5 gallons 7 gallons
Using cross products
116*7 = 5x
Divide by 5
812 /5 = 5x/5
162.4 =x
162.4 miles
5/8 = x/9
cross multiply
8x = 5 * 9
8x = 45
x = 45/8
x = 5.625....rounds to 5.6
42 = 40(x-1) + 40
x-1 will be equal to the sales tax rate in this equation.

Answer:
Option D. a^2+6ab-2ba
Step-by-step explanation:
Option D because we have like terms: 6ab and -2ba=-2ab, then
a^2+6ab-2ba=a^2+6ab-2ab
Simplifying on the right side of the equation adding like terms:
a^2+6ab-2ba=a^2+4ab
