Wendy is arranging books on the bookshelves in the school library. The total number of books she arranges is given by the equation b=12, where b is the total number of books and r is the number of rows. Each row contains the same number of books.

Answer 1

If you are supposed to show an expression showing this it would be:

b * r = x

B is the total number of books. R is the number of rows. X is the total.

You need to add what you are suppose to do in this question, right now it is just a statement really. I hope this helps!

Answer 2

Answer:

Hey there! The answer is 192

Step-by-step explanation:

Given :Wendy is arranging books on the bookshelves in the school library. The total number of books she arranges is given by the equation b = 12r, where b is the total number of books and r is the number of rows. Each row contains the same number of books.

To Find: If Wendy arranged 16 rows, she arranged a total of ___ books.

Solution:

Since we are given an expression:

b = 12r

where b = total no. of books she arranged

r denotes the number of rows

Since we are asked  If Wendy arranged 16 rows, she arranged how many books

So, put r = 16 in equation

Thus b = 12*16

b=192

Therefore, she arranged 192 books in 6 rows
