-7x+12-2x=23+13x
First take away 13x from the right side and put it on the left side adding taking it away from -7x
-7x(-13x)=-20x
-20x+12-2x=23
then add 2x to -20x
and move 12 to the other side, minus it off of 23
-18x=11
then divide -18x on both sides
then x=-11/18
Answer:
Monokuma
Step-by-step explanation:
The sum of the interior angles of the polygon = (n - 2) x 180 .
(n - 2) x 180 = (n x 150)
180n - 360 = 150n
Add 360 to each side:
180n = 150n + 360
Subtract 150n from each side:
30n = 360
Divide each side by 30 :
<u>n = 12</u>
To find the answer you need to find the common factor of numbers 25 and 60
25,50,75,100,125,150,175,200,225,250,275,300
60,120,180,240,300
