Question

the formula a= d/g gives the average gas milege a of a vehicle that uses g gallsons of gas to travel d miles. use the formula to find how many gallons of gas a vehicle with average gas mileage of 20.2 miles per gallon will use to travel 75 miles. round your answer to the nearest tenth.

Answer 1

Just use the values they give you in the formula given...

a = d / g a = gas mileage, d = miles, g = gallons

Answer 2

i dont get it....

Answer 3

so, you are given that a = 20.2, the distance is d = 75, and you need to find g.

20.2 = 75 / g

Answer 4

so would you multiply by 75

Answer 5

You need to solve for g, so you need to not have it in the denominator.

Multiply both sides of the equation by "g"
20.2 = 75 / g
20.2 * g = g * 75/g
Then simplify the right side:
20.2 * g = 75

Finally, you need to divide both sides by 20.2 to get g all alone on the left:

g = 75 / 20.2

Answer 6

do u need to diveide 75/20.2

Answer 7

yes, that's right... you divide 75 miles by 20.2 miles per gallon to get the answer.

Answer 8

so 3.7 gallons?

Answer 9

That's what I get :)
