Answer:
- first car: 25 mpg
- second car: 15 mpg
Step-by-step explanation:
Let x represent the fuel efficiency of the car that used the most gas. Since the sum of the fuel efficiencies is 40 mpg, the other car had a fuel efficiency of (40-x). Then the combined miles driven is ...
40x +25(40-x) = 1225
15x = 225
x = 15
(40-x) = 25
The first car got 25 miles per gallon; the second car got 15 miles per gallon.
_____
We made use of the relation ...
gallons × (miles/gallon) = miles
We have that
<span>13.5x+m =2.7(5x-3.6)
</span>13.5x+m =2.7*5x-2.7*3.6<span>
13.5x+m=13.5x-9.72
</span>if the expression (13.5x+m) is equivalent to 13.5x-9.72
then
m=-9.72
the answer is
m=-9.72
