<em>The question has missing details. However, general questions that could be asked is as follows:</em>
<em>(1) The number of miles traveled after using (say) 5 gallons</em>
<em>(2) The number of gallons used after traveling for (say) 36 miles</em>
Answer:

Step-by-step explanation:
Given

A linear equation is represented as:

Where
and

c, in this question represents the initial capacity of the tank.
So, the initial capacity is 120 liters
Solving (a): r = 5




<em>60 miles traveled</em>
Solving (b): s = 36


Collect like terms


Solve for r

<em>42 gallons used</em>
$8.50 because if he worked 40 hours a week you would multiple that by 52 because there are 52 weeks in a year. From there you would take the total he made and divide it by the hours he worked.
Step 1- Find the Greatest common factor (GCF)
GCF = 3
Step 2- Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3(15x^xy^2/3 + -3x^3y/3 + 75x^4/3)
Step 3- Simplify each term in the parentheses
3(5x^xy^2 - x^3y + 25x^4)
