A car travels 150km in 12L if gasoline. How many liters of gasoline are needed to travel 500km?

40 liters

Step-by-step explanation:

We know that the car travels 150km in 12l of gasoline. To find how many liters of gasoline are need to travel 500km, we simply make a proportion equation.

First, lets write down what we know . . .

1.) 12L of gas = 150km

2.) ?L of gas = 500km

Now since we have the two proportions, its time to add them into an equation and solve them. In this equation, I will use fraction to compare both.

1.)      (Liters on top, km on the bottom)

2.)        (Solve the equation using cross-muliplication)

3.) 150 × X = 12 × 500      (Cross multiplied)

4.) 150x = 6000       (Solve Algebraically)

5.)         (Divide both sides by 150 to cancel out the 150 (rule))

6.) x = 40       (Answer)

okay wait before i answer, is this for your points on a graph?

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
