c) True

m is odd then m= 2n+1

l is even so l = 2p

Sum = 2(n+p)+1  hence odd

The library at school is organized By fiction and nonfiction books. There are 3 non-fiction books for every 7 fiction books how
OLEGan [10]

You can set up a proportion for this problem. Let the total number of books = x

The number of non-fiction books to the total number of books is

3/(7 + 3) books = 3/10

3/10 = 240/x                       Cross multiply

3x = 240 * 10                      Combine the right

3x = 2400                           Divide by 3

3x/3 = 2400/3                    Divide

x = 800

Answer: 800 books in total.
