There are k students in the class. m of them are girls. How many boys are in the class? How many more boys than girls are there? HELP

Step-by-step explanation:

If there are total of k students in a class, and m of those students are girls, the total amount of boys would be:

(Where k, m, b are variables that represent the total number of students, the amount of girls and the amount of boys respectively)

As the amount of girls subtracted from the total amount would leave you with the amount of boys.

There would be:

more boys than girls.

If there were 10 total students in the class and 3 of those students were girls, lets use our above equations to see if they are correct - and if we get the expected amounts of:

7 boys in the class, and 4 more boys than there are girls.

This is correct, as we expected this amount.

The difference between them is 4, so this is correct.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
