7x + 1
Combine like terms: 2x + 5x
Then add the remaining terms: 7x + 1
Inequalities are used to relate unequal expressions
The greatest whole number of square yards the teacher can buy is 4
The inequality is given as:
![8x + 10y \le 120](https://tex.z-dn.net/?f=8x%20%2B%2010y%20%5Cle%20120)
When the <em>number of square yards </em>of the white fabrics is 10.
It means that: x = 10
So, we have:
![8 \times 10 + 10y \le 120](https://tex.z-dn.net/?f=8%20%5Ctimes%2010%20%2B%2010y%20%5Cle%20120)
![80 + 10y \le 120](https://tex.z-dn.net/?f=80%20%2B%2010y%20%5Cle%20120)
Collect like terms
![10y \le 120 - 80](https://tex.z-dn.net/?f=10y%20%5Cle%20120%20-%2080)
![10y \le 40](https://tex.z-dn.net/?f=10y%20%5Cle%2040)
Divide both sides by 10
![y \le 4](https://tex.z-dn.net/?f=y%20%5Cle%204)
The above inequality means that:
The greatest whole number of square yards the teacher can buy is 4
