Agroup of 53 friends meets for lunch. they greet each other by exchanging fist bumps. how many fist bumps are exchanged if each friend must bump with each of the 52 others?

There are 53 people. The formula is

Bumps = n*(n - 1)/2

n = 53

bumps = 53*52/2 = 1378 bumps. Here's a question for you. Can you ever get an odd number of bumps? The answer is no.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
