: Ashley is 64 years old and Stephanie is 18 years old. How many years will it take until Ashley is only 3 times as old as Stephanie?

Step-by-step explanation:

It will take 5 years because when you add 5 to Stephanie's age = 18 + 5 = 23

And Ashley age = 64 + 5 = 69

So when you multiply 23 by 3 = 69

This means after 5 years Ashley will be 3 times as old as Stephanie

i believe that the slope of the line is -5

step-by-step explanation:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
