Two angles are complementary when they add up to 90 degrees<span>
</span>Two angles are supplementary when they add up to 180 degrees
angle = x
supplementary angle = (180-x)
complementary angle = (90-x)
180 - x - 40 = 2(90-x)
140 - x = 180 - 2x
-x + 2x = 180 - 140
x = 40°

Answer:
Step-by-step explanation:
4x - 3/2 - 5 - 2x/3 - 3x - 4/3 = 5
Give all terms least common denominator of 6:
4x(6/6) - 3/2(3/3) - 5(6/6) - 2x/3(2/2) - 3x( 6/6)- 4/3(2/2) = 5(6/6)
24x/6 - 9/6 - 30/6 - 4x/6 - 18x/6 - 8/6 = 30/6
Combine x terms and numerical terms:
2x/6 - 47/6 = 30/6
2x/6 = 77/6 (Add 47/6)
2x = 77 (Multiply both sides by 6)
x = 77/2 = 38.5
Answer:
6(-3+7x)
Step-by-step explanation:
Factor out 6 from each term
- 6*3 + 6*7x
6(-3+7x)
