Answer:
-20
Step-by-step explanation:
Do the math in the parenthesis first
(5-21) = -16
(3+1) = 4
Rewrite the problem
- 16 - 4= -20
The answer is -20
Answer:
These parallel lines cross 1 line. Because they are parallel they will form the same angles on that line. Therefore, x+50 = 3x-100 since those angles are corresponding angles made by a pair of parallels.
To find x we need to find what value of x gives the same answer for 3x-100 and x+50 since those 2 angles are equal.
x+50 = 3x-100 - now all we need to do is solve for x:
x+50 = 3x-100
50=2x-100
150=2x
75=x
x=75
