Step-by-step explanation:
-2x + 9 < x − 9
Add 2x to each side
2x-2x + 9 < 2x+x − 9
9 < 3x-9
Add 9 to each side
9+9 < 3x
18 < 3x
Divide each side by 3
18/3 < 3x/3
6 < x
Open circle at 6 line going to the right

Answer:
y = 72.5
x = 35.
Step-by-step explanation:
First Off, Let's Divide the question.
<em><u>Let's Find the variable y : </u></em>
<em><u /></em>
there are 2 y(s), so it is 2y.
equation: 2y +35 =180.
I put 180 because A straight Line is always 180.
2y+35=180
<u><em>1. Subtract both sides. </em></u>
2y = 145
y = 72.5
<u><em>Next,Find x </em></u>
So y + y + x = 180.
We already know y, which is<u> 72.5</u>
72.5 +72.5 + x = 180
72.5 +72.5
x + 145 = 180
x = 35.
Hope This Helps!
The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10
