The sum of the interior angle of a polygon is 720°, thus the value of w will be obtain as follows:
size of each angle is
720/6=120°
thus
8w=120
solving for w we get'
(8w)/8=120/8
w=15°
Answer: w=15°
The answer is B. (2 + x) + 3y.
The associative change happened when they just moved the parenthesis.
Hope this helps!
I'm not 100% sure but I believe it's $250
9 + (3 x 4) - 6 + 12/3 3 makes 12 4 times which is why 12/3 is 4
9 + 12. -6. +. 4
21 - 6 + 4
15+4 = 20
The answer is B. y = -1/5x +1/2.
EXPLANATION
First solve for the slope:

After finding the slope, look for the linear equation with the same value of m (parallel equation).
