So the teacher bought 1/4 of the brownie pan. And it came out to $4.
I hope this helps! :)
I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a
The first one is the answer/
The larger number is 10 - x.
2(10 - x) - (-20)
20 - 2x + 20
40 - 2x
