60 people take a driving test one fifth of them fail how many fail

12

Step-by-step explanation:

1/5 of a whole means divide the whole by 5.

60 divided by 5 equals 12 to confirms this do 12 times 5.

12 times 5 = 60.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

hello! just here for points! though i wish i knew!
