Answer:

y = 60 when x = 12

Step-by-step explanation:

Direct variation is

y = kx

15 = k3

Divide by 3

15/3 = k

5 =k

y = 5x

Let x = 12

y = 5*12

y = 60

You and your friend collect 180 cans for a food drive. The ratio of cans you collected to cans your friend collected is 4 to 5.
marissa [1.9K]
Are you looking for the number of cans you and your friend each collected? If yes, here is the solution:

Let x be the number of cans.

4x + 5x = 180
        9x = 180
     9x/9 = 180/9 (divide both sides of the equation by 9)
          x = 20

Now, substitute the values:
4(20) + 5(20) = 180
       80 + 100 = 180
               180 = 180

Therefore, you collected 80 cans and your friend collected 100 cans.
