Answer:
You will need 34 square feet of carpet
2(x+10)+3x=85
2x+20+3x=85 I used Distributive property
(2x+3x) +20=85 Combine like terms
5x+20-20=85-20 now i need to get rid of the 20 so i subtract it (the reason for this is because it is positive you have to so the oposite, in this case subtract) from that side, and what you do to one side you have to do to the other
5x=65 is what you have now
5x/5=65/5 Now i need to get rid of the 5 by divition, so i do it to both sides
x=13 is the answer
Branliest please!!!
The percentage decrease is 16.667%
72-60=12
12/72 =0.166
0.1666×100%
16.667%
At any value of x, Bruce would have always used 3 tiles less than Felicia.

What is an expression?</h3>
- In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to context-dependent norms.
Calculate to explain:
- Number of tiles Bruce used: 5x + 2
- Number of tiles Felicia used: 5x + 5
- On equating the two expressions:
- 5x+2 = 5x+5
So, there is no solution.
Any value of x, Bruce would have always used 3 tiles less than Felicia.
Therefore, at any value of x, Bruce would have always used 3 tiles less than Felicia.
