Holly collects video games. She starts with 3x3 games, for some number x, and then buys another 7x4 She then gives away x?, then sells 5x, and finally donates
another 9 games. Write an expression for the number of games Holly now has in
standard form.
0-9 – 5x – x2 + 3x3 + 7x4
7x4 + 3x3 – 22 – 5x – 9
-9 + 7x4
5x + 3x3
22

3x3 – 5x + 7x24 – 9 – 22

factor trees are nice.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

what level of math? also i don't need to be paid if i can you.

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
