Answer 13

Yes. Add them together.

Answer 14

x = 9

Answer 15

So it would be...\[10x*10\]

Answer 16

How did you get 9?

Answer 17

10 + 10 = 20 * x =9 20*9=180

Answer 18

nvm its not 9

Answer 19

When you have a straight line as shown is always equals 180 so

(2x+9)+(8x+1)=180

So first you combine like terms-

9+1=10 and 2x+8x+10x
so 10+10x=180
then you subtract 10 from both sides (what you do from one side you do to the other)

10x+10-10=180-10

Then you get 10x=170

Then you divide 170 by 10x

and 170 divided by 10 =17

So your answer is 17
