Answer:
1/6 + 1/5 = 1/x, 3 days
Step-by-step explanation:
a) x days will take to paint the house together.
b) 1/6 part of the house, Noah paints for 1 day.
1/5 part of the house, Owen paints for 1 day
1/x part of the house they paint for 1 day together, and also we can write that
(1/6 + 1/5) part of the house they paint for 1 day together.
So, we can write equation
1/6 + 1/5 = 1/x
c) 1/6 + 1/5 = 1/x
30x*1/6 + 30x*1/5 = 30x*1/x
5x + 6x = 30
11x = 30
x = 30/11 ≈2.72 ≈ 3 days
