Answer:
Therefore, Steve will paint house for 20.6 days.
Step-by-step explanation:
We know that Steve determines that it would take them 9 days to paint the house together (if they were both healthy) and that it would take Janet (when healthy) 16 days to paint the house alone.
We conclude that in 1 day Janet painted 1/16 of the house. In nine days, Janet painted 9/16 of house.
So, 7/16 of house paint Steve in nine days.
We have the following proportion:

Therefore, Steve will paint house for 20.6 days.

Step-by-step explanation:
We require 2 equations with the recurring part after the decimal point.
Let x = 0.555..... → (1)
Multiply both sides by 10, then
10x = 5.555..... → (2)
Subtract (1) from (2) thus eliminating the recurring decimal
(10x - x) = (5.5555 - 0.5555 ), that is
9x = 5 ( divide both sides by 9 )
x = 
Absolute value
at x=2, the absolute value thing is positive
do this one

the derivitive is

so the slope at x=2 is

=-3
a point is (2,2)
point slope form
y-y1=m(x-x1)
y-2=-3(x-2)
or
y=-3x+8
das is de equation
The answer is 27 inches. I am 90% sure of it. It is 27 because a yard has 36 inches. So you do the rule of three. 36/4*3. 36/4 is 9. 9*3=27. I hope you pass your test! :D
