The two angles together form a straight angle, i.e. an angle of 180 degrees. This means that

$7x + 2x+27 = 180$

Sum like terms:

$9x+27 = 180$

Subtract 27 from both sides:

$9x = 153$

Divide both sides by 9:

$x = \dfrac{153}{9} = 17$

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.
