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!

Answer:

14 and 4/1000 or 14004/1000

Step-by-step explanation:

1*10+3*1+4*(1/1000)

First i like to separate the equation by PEMDAS or order of operations. First is parentheses, which is the fraction. Then is exponents. There is none. Then multiplication and division so u solve 1*10, 3*1 and 4*1/1000.

This is the updated equation: 10+4+(4/1000)

Next you do subtraction and addition. The order does not matter if there's only addition. If there is subtraction u solve by the order of the equation. SO in this step we solve 10+4+(4/1000)

Here is the updated version: 14+(4/1000)

Then u add that which is 14 and 4/1000 or you can do 14004/1000
