Hannah's school hosted a book donation. There are 150150150 students at her school, and they donated a total of bbb books! Hannah donated 333 times as many as the average number of books each student donated. How many books did Hannah donate

Hanna donated b/50 books

Step-by-step explanation:

In this problem, we have:

n = 150 number of students at Hanna's school

b = ? number of total books donated by the students

Also, Hannah has donated 3 times as many as the average number of books each student donated.

The average number of books each student donated can be written as:

And calling

h = number of books donated by Hannah

This means that

Simplifying, this can be rewritten as

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
