We have this equation:

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:


Then, dividing the equation by 2:

Finally, let's order this equation:
Answer:
C. corresponding angles
Step-by-step explanation:
I think this because 1 and 5 are on the same side and they're angles formed by the transversal line that cuts across
4 people x 45 minutes = 180 minutes total to paint 5 walls
180/5 = 36 minutes of man work per wall
36 * 4 walls = 144 total minutes
144/6 people = 24 minutes total
