Answer:

If the expression is 2y+9x the answer is: 10x+12y

If the expression is 2y-9x the answer is -8x+12y

Step-by-step explanation:

You would combine all your x values:-4,9,9,-4 and that equals 10 then you would add your variable, so your x value is 10x.

You would then combine all your y values: 8,-2,8,-2, and that equals 12, then you would add your variable, so your y value is 12y.

Answer:

x+14y-18xy

Step-by-step explanation:

1) Multiply terms if needed.

2) Group your terms by variables. (x with x, y with y, xy with xy, etc.)

3) Add like terms (terms with same variables)

This problem will look like:

Step one: take the term "-2y9x" and multiply to creat one term (You have to remember PEMDAS with these problems. Look it up if you don't know what it is :) ) You should come up with -18yx for this term.

Step two:  Organizing terms --->   9x-4x-4x+8y+8y-2y-18xy

Step three: Take your like terms and add them together. Your answer should end up being x+14y-18xy

telo118 [61]
Customer #2 has the smallest total bill, including tax and tip.
Choice A, 1.06b + 0.16(1.06b), is correct.
Customer 3's bill is approximately 10% less than customer 1's bill.
Customer 2 leaves the bigger tip.

For customer #1:
(1.06(12.95))(1.15) = 15.79; the tip is 0.15(1.06(12.95)) = 2.06.
For customer #2:
1.06x = 11.65; x = 10.99; 20% tip = 0.2(10.99) = 2.20; total = 11.65+2.20 = 13.85.
For customer #3:
1.06(11.50) + 0.18(11.50) = 14.26; the tip is (0.18)(11.50) = 2.07.

Customer 3 spends 15.79-14.26 = 1.53 less than customer #1, which is 1.53/15.79 = 0.097 ≈ 10% less.
