Answer:
22
Step-by-step explanation:
Given:
An art teacher has the total number of buttons = ![b](https://tex.z-dn.net/?f=b)
1. In order to give each in the class 6 buttons, she will need 18 more buttons.
2. If she gives each child 5 buttons, she will have 4 left over.
Question asked:
How many children are in the class ?
Solution:
<u>Let total number of children in the class = </u>![x](https://tex.z-dn.net/?f=x)
<u><em>As given that, 18 more buttons will be needed to give 6 buttons to each.</em></u>
The equation will be:-
![b+18=6x\\b-6x=-18\ (equation\ 1)](https://tex.z-dn.net/?f=b%2B18%3D6x%5C%5Cb-6x%3D-18%5C%20%28equation%5C%201%29)
<em><u>Also given that, If she gives 5 buttons to each, she will have 4 left over.</u></em>
The equation will be:-
![b-5x=4\ (equation\ 2)](https://tex.z-dn.net/?f=b-5x%3D4%5C%20%28equation%5C%202%29)
Subtraction equation 2 from 1
![b-6x-(b-5x)=-18-4\\b-6x-b+5x=-22\\-6x+5x=-22\\-x=-22\\Minus\ canceled\ by\ minus\\x=22](https://tex.z-dn.net/?f=b-6x-%28b-5x%29%3D-18-4%5C%5Cb-6x-b%2B5x%3D-22%5C%5C-6x%2B5x%3D-22%5C%5C-x%3D-22%5C%5CMinus%5C%20canceled%5C%20by%5C%20minus%5C%5Cx%3D22)
Hence, total number of children are 22.
All you need to do is do $23 divide by %13. (Which you are dividing 0.13 23.
