Veronica drove 294 miles and used 12 gallons of gasoline, how many gallons of gas would it take her to drive 490 miles?

20 gallons

Step-by-step explanation:

To solve, we can use a proportion

She used 12 gallons for 294 miles, and x gallons for 490 miles

12/294=x/490

Cross multiply

294*x=12*490

294x=5880

We want to solve for x. To do that, we need to get x by itself. Since x is being multiplied by 294, divide both sides by 294.

294x/294=5880/294

x=20

So, she needs 20 gallons to drive 490 miles

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
