Answer:
x=13
Step-by-step explanation:
Angle A and angle B are supplementary
Supplementary angles add to 180 degrees
<A + <B = 180
7x-18 + 8x+3 = 180
Combine like terms
15x -15 = 180
Add 15 to each side
15x-15 +15 = 180+15
15x = 195
Divide by 15
15x/15 =195/15
x =13
The commutative property is when you are switching the order of the numbers/variables, and the associative property is when you switch the grouping. So for the first line, the answer would be the the associative property, the second line is the commutative property, and so on and so forth. Does this help you?
