Answer:
12x6+2(6-1)
72+2x5
72+10
82
82 is the answer.
Step-by-step explanation:
Just replace the X's in the problem with 6.
"Fuel economy" = "miles per gallon" = (distance traveled) divided by (gallons used)
mpg = (226 miles) / (10.5 gallons) = <u>21.52 miles per gallon</u> (rounded)
It makes absolutely no difference whether the trip took 4 hours or 4 years.
That information is there just to try and trip you up. You don't need it.
