The answer would be B) Car A travels more miles per gallon of fuel than Car B.
This is because Car B is shown on the graph to travel the same number of miles as Car A using 16 gallons of fuel, while Car A uses only 4 gallons. Thus, Car A travels further with less fuel. For problem 3: Let's write out the equation and try to solve. 5x + 1 = 3x + 7
First, subtract 3x from both sides. 5x - 3x + 1 = 3x - 3x + 7 2x + 1 = 7 Now, subtract one from both sides.
