Answer:
x=-9
Step-by-step explanation:
2(x-7)-5x=13
Remove the parenthesis
2x-14-5x=13
Collect like terms
-3x - 14 = 13
Move the constant to the right
-3x=13+14
Calculate
-3x=27
Divide on both sides to get the answer

Step-by-step explanation:
1,200 x .125 = 150
Answer:
12 sides
Step-by-step explanation:
To find the number of sides of a regular polygon with the sum of interior angles of 1800 degrees, we will follow the steps below;
first write down the formula for finding sum of the interior angle of a polygon
s= (n-2)180
where s is the sum of the interior angle and n is the number of side
from the question given, sum of the interior angle s=1800 degrees
substitute s=1800 degree into the formula and solve for n
s= (n-2)180
1800 = (n-2)180
divide both-side of the equation by 180
1800/180 = n-2
10 = n - 2
add 2 to both-side of the equation
10 + 2 = n
12 = n
n= 12
The polygon have 12 sides
(x+y)0
(-3+5)0
(-15)0
THE ANSWER IS 0 BECAUSE YOU ARE MULTIPLYING BY 0
