Answer:

2x = 40°

3x = 60°

4x = 80°

Step-by-step explanation:

2x+3x+4x = 180°

9x = 180

x = 20

2x = 2(20) = 40°

3x = 3(20) = 60°

4x = 4(20) = 80°

Answer:

-4y + 20

Step-by-step explanation:

4(-y+5)

What we need to do here is get rid of the parentheses, which can be achieved through multiplication.

This is another way of saying 4 times -y plus 4 times 5.

Let's break the the parentheses down into 2 separate formulas.

4(-y) and 4(5)

Now we can multiply these two together to get -4y and +20. When combined, we get -4y +20.
