You take your miles driven divided by the gallons of gas used.
So,
254.6 miles/19 gallons = 13.4
The gas mileage of the car is 13.4
Hope this helps :D
Answer:
Yes
Step-by-step explanation:
6 + 8y - 3+ 4y
Add like terms
(8y+4y)+(6-3)
12y+3
Write an equation, calling the number x:
3x=2(x+4)
3x=2x+8
x=8
However, 8 is not a perfect square, which was required in the problem, so there are no solutions.
