1.)18 = 2(4 + x) ||
2.) 18 = 8 + 2x --- Distribute. ||
3.) 10 = 2x --- Isolate the variable by collecting like terms ||
4.) 5 = x
I'd say A. is a good choice.
The answer would be 2/5 because you have to put in a slope equation which gives you your answer.

Step-by-step explanation:
Answer:
It takes 46 minutes for 10 people to paint 3 walls
It takes 92 minutes for 10 people to paint 6 walls (twice as long because you have twice as many walls)
You only have 4 people to paint the walls instead of 10 people
Therefore it will take 2.5 times as long (10/4=2.5)
2.5*92=230 minutes
My answer is a and c becuase they equal the same on each side
