Answer:
$40
Step-by-step explanation:
If he spent $40 and has none left that means he currently has $0.
If you subtract $40 - b = $0
b = $40
X is 57
That means y is 36.
Sorry, I’m gonna try not explain it because I’m rlly bad at explaining and all I’m going to do is confuse you even more...
To start, first distribute the x's to their expressions. This would look like this:
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x
2 7.5
That’s all that I could do I hope it help
The answer is 1 computer/8 students
