Vehicle A gets 39 miles per 1.5 gaons of fuel. How many miles could it get on 3.5 gallons of fuel

91 miles

Step-by-step explanation:

Let's make a proportion

miles/gallons=miles/gallons

The vehicle gets 39 miles on 1.5 gallons, and x miles on 3.5 gallons

39 miles/1.5 gallon= x miles/3.5 gallons

39/1.5=x/3.5

Now, we need to solve for x. To do this, we have to get x by itself. x is being divided by 3.5 To undo this, multiply both sides by 3.5, because multiplication is the opposite of division.

3.5*39/1.5=x/3.5*3.5

The 3.5s on the right cancel, so we are left with:

3.5*39/1.5=x

3.5*26=x

91=x

The vehicle gets 91 miles on 3.5 gallons of fuel

9 x 8 divided by (5-3)=36
