Answer:
Let B have x days work:
A + B = 3 days
1/4 + 1/x = 1/3
1/3 - 1/4 = 1/x
1/12 = 1/x
x = 1 / (1/12)
x = 12
B takes 12 days

Step-by-step explanation:
5 2/7 as improper fraction is 37/7 and it equals 5.28571428571 which makes it repeating because the numbers don't stop.
7/16 is equal to 0.4375 making it terminate because the numbers stop.
14 5/9 as an improper fraction is 131/9 and 131/9 is 14.5555555556 and that is a never ending pattern so it is repeating.
3/22 is equal to 0.13636363636 it is repeating because the numbers never stop.
A) To find x for f(x) = 0, substitute the given information and solve for x.
.. f(x) = 0 = -0.5x +2.5
.. 0.5x = 2.5 . . . . . . . . . . add 0.5x
.. x = 2.5/0.5 = 5 . . . . . . divide by the coefficient of x
f(5) = -0.5*5 +2.5 = 0
b) f(0) = -0.5*0 +2.5 = 2.5
