You can use at most 24 beads that are 10 inches long to decorate the rope.
Step-by-step explanation:
Given,
Length of rope = 120 feet
1 foot = 12 inches
20 foot = 20*12 = 240 inches
Length of bead = 10 inches
Let,
x represents the number of beads used on rope.
As the rope is 240 inches long, therefore, the total length of beads cannot exceed 240 inches.
Length of each bead*Number of beads ≤ length of rope
![10*x\leq 240\\10x\leq 240](https://tex.z-dn.net/?f=10%2Ax%5Cleq%20240%5C%5C10x%5Cleq%20240)
Dividing both sides by 10
![\frac{10x}{10}\leq \frac{240}{10}\\x\leq 24](https://tex.z-dn.net/?f=%5Cfrac%7B10x%7D%7B10%7D%5Cleq%20%5Cfrac%7B240%7D%7B10%7D%5C%5Cx%5Cleq%2024)
You can use at most 24 beads that are 10 inches long to decorate the rope.
