On a trip across the country Joe used 20 gallons of gas to go 300 miles. At this rate, how much gas must he use to go 3600 miles? HELP

240 gallons

Step-by-step explanation:

Let's set up an ratio where g = gallons and m = miles:

20g = 300m

We need the right side of that to be 3600, so multiply both sides by 12:

12(20g) = 12(300m)

240 gallons for 3600 miles

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
