Answer:
b should be the correct answer.
Step-by-step explanation:
Using the Vertical Angle Theorem 4x + 7 is equal to 5(x - 4).
Solve for x.
4x + 7 = 5(x - 4)
4x + 7 = 5x - 20 <-- Distribute the 5
4x = 5x - 13 <-- Subtract 7 from each side
-x = -13 <-- Subtract 5x from each side
x = 13 <-- Divide both sides by -1
So, x is equal to 13.
Answer:
67
Step-by-step explanation:
ad 71 and 42 113 then take that away from 180.
If there were two electricians, they'd need to install 48 fixtures per person.. if it takes 20 minutes for each fixture, it would take a total of 960 minutes, which converts to 16 hours. If a work day was only 8 hours, it would take two electricians TWO work days to install 96 light fixtures, or 24 light fixtures for four floors.
The length is 12, because if it's 9 inches wide it has two sides of 9 inches which is 18. Then subtract that from the intial value 42 to get 24. After, you divide 24 by 2 due to there being 2 sides of the box and 24 is the sum of both sides. Hopethis helps!
