Hey, hope you're doing great today :)

Let's learn about what we need to learn to solve our equation.

We need to make this into a y=mx+b form.

That's the main thing you need to understand while doing this.

Now let's get onto the problem!

This is to much big of an equation to set up, so we need to change some things up.

We need to make one thing into a fraction.

It should look like y = -3/5x + 8.

This is in correct y = mx + b form.

Hopefully that clears things up :)

In a group of eighteen people, each person shakes hands once with each other person in the group. How many handshakes will occur
miv72 [106K]

The number of handshakes that will occur in a group of eighteen people if each person shakes hands once with each other person in the group is 153 handshakes

In order to determine the number of handshakes that will occur among 18 people, that is, the number of ways we can choose 2 persons from 18 people.

∴ The number of handshakes = ^{18}C_{2}

^{18}C_{2} = \frac{18!}{(18-2)!2!}

^{18}C_{2} = \frac{18!}{16!2!}

^{18}C_{2} = \frac{18\times17\times16!}{16!\times2!}

^{18}C_{2} = \frac{18\times17}{2\times1}

^{18}C_{2} = \frac{306}{2}

^{18}C_{2} = 153

∴ The number of handshakes = 153 handshakes

Hence. 153 handshakes will occur in a group of eighteen people if each person shakes hands once with each other person in the group.

PLEASE HELP ME!!!! ASAP PLEASE!

Answer:

We know that since it's a square, the lenght size is the same on all sides. We can simply use pythagoras theorem:

a^2 + a^2 = 13.5^2

13.5^2 = 182,25‬

182,25 : 2 (because there are 2 'a') = 91,125

<u>The square root of 91,125 is 9,55 feet.</u>

ludmilkaskok [199]

Hello,

John : n

Brad : n + 12

n + n + 12 = 84

2n + 12 = 84

2n = 84 - 12

2n = 72

n = 72/2

n = 36

John $36 and Brad $36 + $12 = $48
