Asap for 10 and 11 (show work+lots of points)

One gallon of gas =44.8 miles
She put in 5 gallons
So do 5 times 44.8
which equals 224 miles

I'll go ahead and do number 11. To get the miles per hour of each race, divide the miles by the hours. For the first one, 372.5/2.5 is 149 mph. For the second one, 460.8/3.2 is 144 mph. He drove a faster average speed in the first race, because it had a higher number of miles per hour.

4should be the last one n=4

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
