Catherine 168 pieces of gum playing at a bean bag toss in the county fair at school she gave three to every student in her math class she has 8 remaining how many students are in her class

Givens

Let the number of students in the class be x

Let the number of pieces of gum she gave out be 3x

Equation

3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.

3(x - 1) + 8 = 168      This doesn't work either.

Well we have to choose. It's a rounding problem.

3x + 8 = 168     Subtract 8 from both sides.

3x = 168 - 8      Combine

3x = 160           Divide by 3 on both sides.

x = 160 / 3

x = 53.333333333

Since that can't be, we could say there were 53 students.

3x

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
