Supplementary angles will always add up to 180. If you had a straight line, and you drew another line across that line, the two angles on either side of that line would add up to 180 because a flat line is equal to 180 degrees.

Answer:
y = 49 1/3
Step-by-step explanation:
1/8y-2/3=5.5
1/8y = 5.5 + 2/3
multiply both sides by 8:
y = 8(5.5 + 2/3) = 44 + 16/3 = 44 + 5 1/3 = 49 1/3
Answer: 8+18W
Step-by-step explanation:
1. First multiply the 4 by 2, equalling 8.
2. Then multiply the 9W by 2, equalling 18W.
3. 8 and 18W are unlike terms, so they can not be added together.
4. The answer would stay as 8+18W.
