Answer:
a. 13xyz + 9 + 2xyz + 3
13xyz+2xyz+ 9+3 ( combine like terms)
15xyz+12
b. 6ab + (–2ab) + 4 + 6
6ab-2ab+4+6
4ab+10
Answer:

Step-by-step explanation:
1 out of 100 is 1 percent and 9 percent is much larger
For graphing make sure to shade the right portion and to make the line dotted like (— — — —)
the red is y>8x-4, the blue is y>-1/2x+1/2
2x-.25y < 1 is equal to 2x-1/4y < 1
multiply each side by 4:
8x-y < 4
add y to each side:
8x < 4+y
subtract 4 from each side:
8x-4 < y
rewrite:
y > 8x-4
4x+8y > 4
divide both sides by 8:
1/2x+y > 1/2
subtract -1/2x from each side:
y > -1/2x + 1/2

Order of operations in a simplified version is PEMDAS, which parenthesis, exponents, multiplication/division, addition/subtraction. so in your equation, 180 + (6-2), you start with what's inside the parenthesis to get 180 + 4. then skip MD bc there's no multiplication or division and move to AS. there is addition, so do addition. so your answer would be 184. however, the associative property is applicable here, so using PEMDAS is not required.
