David can finish painting the room in six hours and his elder brother Anthony can finish it in four hours if both brothers paint
lbvjy [14]

Answer:

2.4 hours

Step-by-step explanation:

David's time = 6 hours

Anthony's time = 4 hours

the combined time is given by the following formula

1/ (david's time) + 1/(anthony's time) = 1/total time

1/6 + 1/4 = 1/Total

4/24 + 6/24 = 1/Total

10/24 = 1/ total   (taking reciprocal of both sides)

24/10 = total

total time = 24/10 = 2.4 hours

Hannah's school hosted a book donation. There are 150 students at her school, and they donated a total of b books! Hannah donate
svetoff [14.1K]

Answer:

x=3*\dfrac{b}{150}

Step-by-step explanation:

Let x = number of books that Hannah donated

We know that the number of students is 150 and the total number of books is represented by b, we can write that as:

Average number of books donated by each student = \dfrac{b}{150}

Now we know that Hannah donated 3 times as much as the average. We can write that as:

x=3*\dfrac{b}{150}
