In John's care, the number of miles driven is proportional to the number of gallons of gas used. Gallons of Gas Miles Driven

4 112

6 168

10 280

12 336

A. What is the constant of proportionality?

B. Write an equation that will relate the number of miles driven to the number of gallons of gas.

C. How many miles would John go if he had 22 gallons of gas?

D. How many gallons of gas would he use if he went 224 miles?

(3x-8) or (3x+8)

step-by-step explanation:

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

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu

y = -1

x = 8

hope this !
