Answer:
Down below
Step-by-step explanation:
1. 3/4x-7-16, combine -7 and -16, 3/4x-23
2. -8+2y+4, combine -8 and 4, 2y+4
3. -4x+11x+3y, combine -4x and 11x, 7x+3y
4. 41+b-25b, combine b and -25b, 41-24b
5. -1/2(8x-2), distribute: -1/2*8x and -1/2*-2, -4x+1
6. $40, 15% off: 40(1.00-0.15)= $34
So simplifying expressions means to just combine like terms (e.g. 2 and 4, 5x and -18x, 7y and y, etc.)
Distribution means to apply the multiplication to the terms inside the parentheses (e.g. a(x+y) -> ax+ay)
Sales is just: original price * (1 - percent off by)
I hope this helps!
