Answer:
<h2>x = 12</h2>
Step-by-step explanation:
![\frac{2x - 4}{5} =4](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%20-%204%7D%7B5%7D%20%20%3D4)
First of all multiply through by 5 to eliminate the fraction
That's
![5 \times \frac{2x - 4}{5} = 4 \times 5 \\ 2x - 4 = 20](https://tex.z-dn.net/?f=5%20%5Ctimes%20%20%5Cfrac%7B2x%20-%204%7D%7B5%7D%20%20%3D%204%20%5Ctimes%205%20%5C%5C%202x%20-%204%20%3D%2020)
Next using the addition property add 4 to both sides of the equation
We have
![2x - 4 + 4 = 20 + 4 \\ 2x = 24](https://tex.z-dn.net/?f=2x%20-%204%20%2B%204%20%3D%2020%20%2B%204%20%5C%5C%202x%20%3D%2024)
<u>Divide both sides by 2</u>
![\frac{2x}{2} = \frac{24}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B24%7D%7B2%7D%20)
We have the final answer as
<h3>x = 12</h3>

- 32 x 90= 2880, divide 2880 by 100 equals to 28.8
3. multiply 12 by 62.3
I hope this helps!
To find out the number of necklaces that can be made from 72 and 42 beads, think of the Greatest Common Factor of both numbers
Factors of 72
1 × 72
2 × 36
3 × 24
4 × 18
6 × 12
8 × 9
Factors of 42
1 × 42
2 × 21
3 × 14
6 × 7
The Greatest Common Factor is 6, so there are 6 necklaces can be made with equal number of beads
