Question

Using the equation y = 25x, if x represents gallons and y represents miles, determine how many gallons of gas would be needed to travel 600 miles.

Answer 1

24 gallons

Explanation:

So, the question says:

y = miles

x = gallons

and,

y = 25x and y = 600

First, substitute.

600 = 25x

Divide both sides by 25.

600/25 = x

24 = x

24 gallons are used (or needed) to travel 600 miles.
