A car traveled 63 miles on 3 gallons of gas. What proportion can you set up to determine how many miles, m, the car can travel on 7 gallons of gas?

Respuesta :

Answer:Let x be the number of miles driven on 60 gallons of gas. By setting up and solving a proportion involving x, find the value of x for the car that you have chosen. State the type of car, the mileage, and show both the set up of the proportion and the steps

Step-by-step explanation:

Answer:

147 miles

Step-by-step explanation:

Let x be the number of miles travelled on 7 gallons, then proportion is of the form

[tex]\frac{miles}{gallons}[/tex], thus

[tex]\frac{63}{3}[/tex] = [tex]\frac{x}{7}[/tex] ( cross- multiply )

3x = 63 × 7 = 441 ( divide both sides by 3 )

x = 147

Thus the car can travel 147 miles on 7 gallons
