X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40

Answer:
x = 30.66°
Step-by-step explanation:
The sum of the interior angles of a hexagon is 720°
Each angles are x^0, (5x - 103); (2x + 60), (7x - 31), (6x -6), and (9x - 100),
we add all these angles together
x^0 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100) = 720
x^0 = 1
1 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100)
1 + 5x - 103 +2x + 60 + 7x -31 + 6x - 6 + 9x - 100 = 720
1 - 103 + 60 - 31 - 6 - 100 + 5x + 2x + 7x + 6x + 9x = 720
1 - 180 + 29x = 720
-179 + 29x = 720
29x = 720 + 179 = 889
x = 889/29 = 30.655 ≅ 30.66°
