Angle x is supplementary to the angle with 156 degrees. What this means is that the sum of the two angles is 180 degrees. With this knowledge you can make a formula like so...
156 + x = 180
Now you can solve for x by subtracting 156 to both sides
156 - 156 + x = 180 - 156
x = 24
Hope this helped!

Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
X / 100 = 51.82....multiply by 100 on both sides
x = 51.82 * 100
x = 5182 <== sum of all 100 numbers
Answer:
32
Step-by-step explanation:
77 quarters and dimes
q + d = 77
subtract q from both sides
d = 77 - q
---------------------------
A collection of quarters and dimes is worth $12.50 (1250 cents)
25q + 10d = 1250
substitute for d
25q + 10(77 - q) = 1250
distribute
25q + 770 - 10q = 1250
Combine like terms
15q + 770 = 1250
subtract 770 from both sides
15q = 480
divide both sides by 15
q = 32
