Answer:

A. y = -16

Step-by-step explanation:

Hello!

What we do to one side of the equation we have to do to the other.

y + 7 = -9

We have to get y by itself so we have to get rid of the seven by doing the opposite of what it says

The opposite of addition is subtraction so we subtract 7 from both sides

y + 7 - 7 = -9 - 7

Solve

y + 0 = -16

Simplify

y = -16

The answer is A. y = -16

Hope this helps!

Write an equation that you can use to solve for x. Enter your answer in the box.

patriot [66]

X + 60 = 100 (because they are vertical angles, which means that because they are directly opposite of each other, they are of the same measurements).

Solve for x. Isolate the x, subtract 60 from both sides

x + 60 = 100

x + 60 (-60) = 100 (-60)

x = 100 (-60)

x = 40

40° should be your answer

hope this helps
