Answer:

A. Right a multiple of 2 and up a multiple of 1.

B. (2, 1)

C. the same

Step-by-step explanation:

A. The original point was (2, 1), so if Larissa moves right a multiple of 2 and up a multiple of 1, she'll stay within the ratio.

B. We already know this is proportional, since it goes through the origin; the line just has to pass through the right point: (2,1)

C. The line will be proportional, so as long x is twice as much as y, Larissa will have the same shade of green paint every time.

Jeremy Jax says his car averages 32 miles per gallon of gasoline. How many gallons

Brilliant_brown [7]

Answer:

Step-by-step explanation:

Probably the easiest way to set this up and solve it is to use proportions. We'll put miles on the top and gallons on the bottom:

$\frac{mi}{gal} :$

Since we know the first unit rate of 32 miles per 1 gallon, we put those numbers where they belong in another fraction (ratio), with the number of miles on top with the "mi" and the number of gallons on bottom with the "gal":

$\frac{mi}{gal} :\frac{32}{1}=$

Now we fill in what we know about the second ratio and leave the unknown to be solved for. We want to know how many gallons of gas, x, does he need to travel 500 miles. We put the 500 with the "mi" and the x for "gal":

$\frac{mi}{gal} :\frac{32}{1} =\frac{500}{x}$
