Step-by-step explanation:

y = kx, where k is a real constant.

When y = 12, x = 5.

=> (12) = (5)k, k = 2.4.

Therefore when y = 30,

x = y/k = (30)/(2.4) = 12.5.

The answer is 12.5.

You volunteer at an animal shelter on the weekends and today is adoption day! At the beginning of the event, you start with 44
Angelina_Jolie [31]

6 cats/kittens were adopted.

Step-by-step explanation:

Given,

Number of cats/kittens at the event = 44

Number of cats/kittens adopted = x

Number of cats/kittens returned = Twice returned as adopted = 2x

New total = 50

We will subtract the adopted and add the returned cats/kittens.

Total cats/kittens at event - adopted + returned = New total

44-x+2x=50\\44+x=50\\x=50-44\\x=6

6 cats/kittens were adopted.
