Answer:
We have been given the equation: x+y+z. Now these are variables. Thus, we have to fill in the values given: where x = 18, y = 6 and z = 1. Let's fill these values in.
<em>x+y+z</em>
<em>= 18+6+1</em>
<em>= 18+(7)</em>
<em>= 25</em>

He can make 25 scarves from 15 balls of yarn.
Step-by-step explanation:
Given,
Yarn used for one scarf =
of a ball
Yarn purchased = 15 balls
Let,
x be the number of scarves.
Yarn used for one scarf*number of scarves = Yarn purchased
![\frac{3}{5}x=15](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7Dx%3D15)
Multiplying both sides by ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
![\frac{5}{3}*\frac{3}{5}x=15*\frac{5}{3}\\x=\frac{75}{3}\\x=25](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D%2A%5Cfrac%7B3%7D%7B5%7Dx%3D15%2A%5Cfrac%7B5%7D%7B3%7D%5C%5Cx%3D%5Cfrac%7B75%7D%7B3%7D%5C%5Cx%3D25)
