Answer: 127º
Step-by-step explanation: The sum of internal angles from a polygons is equal to 180 (n-2) where n is the number of sides for the polygon
so the polygon from the picture has 6 sides then the total sum of internal angles is:720º
On the other hand, added all the internal angles we have: 112º+133º+128º+100º+120º=593º
the angle denoted by x is equal to 720º-593º= 127º
3x+17-5x=12-(6x+3)
-2x+17=12-6x-3
-2x+17=9-6x
17=9-4x
8=-4x
x=-2
<u>ANSWER</u>
Commutative property of addition.
<u>EXPLANATION</u>
Let a,b be real numbers. The commutative property of addition states that,

If we let a=-10 and b=6, then

Therefore the given expression demonstrates the commutative property of addition.
The commutative property of addition tells us that, the order in which we add two real numbers does not affect the result.
Answer:
(4, -3)
Step-by-step explanation:
The system of equations can be described a number of ways. One possible description is "a consistent pair of linear equations in two variables."
Perhaps you want to know the solution to this system of equations. I find it easiest to graph them. The attached graph shows the solution to be ...
(x, y) = (4, -3)
__
You can also use "elimination" to simplify the system to a single equation in a single variable. Adding 4 times the second equation to 3 times the first will do that.
3(5x +4y) +4(2x -3y) = 3(8) +4(17)
23x = 92 . . . . . simplify
x = 4 . . . . . . . . divide by 23
Substituting this value into the first equation, we have ...
5(4) +4y = 8
5 +y = 2 . . . . . . divide by 4
y = -3 . . . . . . . . subtract 5
The solution is (x, y) = (4, -3).
