It takes 3 pumps 16 hours to empty a tank
Meaning it takes 48 hours for one pump by its self
So if there are 4 pumps
48/4 it would take them 12 hours
They would need to work 12 hours to do it in 1 day
I believe the answer is 3x5+8x4-2x2-2x
Domain in interval: [6,infinity)
First, subtract 0.6 from both sides of the numbers and then simplify
Then multiply all terms by the same value to eliminate fraction denominators which gives us 2.8
So, n = 2.8
Hope it helps!
Check the picture below
if their areas are equal then A =A or
(3w)(w-2) = (w+1)(w)
solve for "w"
