Simplify 7p+2p-9p anyone know need answer asap

answer:

c 20

step-by-step explanation:

you make 53 a day plus 3.75 per sale

income = 53+ 3.75 s

you want to make at least 128

128 ≤ 53+ 3.75 s

subtract 53 from each side

128 -53 ≤ 53-53 +3.75s

75≤ 3.75s

divide by 3.75 on each side

75/3.75≤ 3.75s/3.75

20 ≤ s

you must make at least 20 sales

13 is not the same as 1/3! the division symbol is not a symbol used to connect two numbers, it is used to find their quotient. for example, 6/2 would be like saying: you have 6 cookies, and 2 friends. how many cookies does each friend get? the answer is obviously not 62, it is 3! so, the exact quotient is 0.3 repeating. you could memorize this or use the fact that 0.9 repeating is 1.

answer:

65/500, 5/8, 2/3, 7/10

step-by-step explanation:

65/500= 0.13

5/8= 0.625

2/3= 0.66 (repeating)

7/10=0.7

answer:

$559.77

step-by-step explanation:

total cost   =

we need to find 4.5% of 525.61. this will be state tax.

we need to find 2% of 525.61. this will be city tax.

converting 4.5% to decimal (4.5 divided by 100) and then multiplying with 525.61 will give us the answer.

state tax =

city tax =

grand total purchase price is 525.61 + 23.65 + 10.51 = $559.77
