Answer:

<u>The answer is G = 20 - m/18, but none of the answers given is correct.</u>

Step-by-step explanation:

1. Let's review the information given to us to help Lulu to answer the question correctly:

Capacity of the gas tank of Lulu's car = 20 gallons

Lulu can travel 216 miles using 12 gallons

2. Which linear equation represents the number of gallons of gas, G, left in the tank after driving m miles?

G = number of gallons left in Lulu's car

m = Miles driven by Lulu

miles per gallon = 216/12 = 18 miles per gallon

Now, we can write the linear equation, this way:

G = Capacity of the gas tank of Lulu's car - miles driven/miles per gallon

Replacing with the values we know:

<u>G = 20 - m/18</u>

Let's assume Lulu drives 180 miles, using our linear equation, we have:

G = 20 - 180/18

G = 20 - 10 = 10 gallons left

Let's assume Lulu drives 54 miles, using our linear equation, we have

G = 20 - 54/18

G = 20 - 3 = 17 gallons left

KengaRu [80]
When you solve proportions, you have to cross multiply.

       9       x
      ---  =  ---         Multiply each numerator by the opposite denominator.
      11      22

(9)(22) = 11x        Then, multiply.

     198 = 11x        Then, divide.

       18 = x
