Simplify 4x + 5y - 13xy - x - 2y

Mathematics
1 answer:
Anarel [89]3 years ago
6 0
Answer: 3x + 3y - 13xy
Move the numbers so that the ones with the same variable can be together :> ( examples of variables: x,y,xy)
4x - x + 5y - 2y - 13xy
You can only do the math if the those numbers are the same example: 4x - x = 3x they both have variable so u can subtract them ( remember x = 1x a variable by itself has a invisible 1 next to it). 5y - 2y = 3y.
-13xy is the only one with the variable xy so we gotta just leave it alone
This leads to our answer:
3x + 3y - 13xy

A restaurant adds a 20% tip to the bills of parties of 6 or more people. Suppose a server waits on five such tables. The bill
castortr0y [4]

Answer:

$218.70

Step-by-step explanation:

You need to first convert the percentage to the decimal.

20% = 0.2

Now, you need to find 20% of each bill by multiplying each bill by 0.2.

0.2(185.45) + 0.2(205.20) + 0.2(195.05) + 0.2(245.80) + 0.2(262.00)

Because of the distributive property, you can add up the bills and multiply the sum by 0.2.

0.2(185.45 + 205.20 + 195.05 + 245.80 + 262.00)

0.2(1093.50)

218.7

The waiter made $218.70 in tips.
