(-5/6x+51/2)-(2/3x+4)

-1.5x + 21.5 (or (43-3x)/2)

Step-by-step explanation:

(-5/6x + 51/2) - (2/3x + 4)

First, find the opposite of 2/3x + 4 because of the negative sign.

-5/6x + 51/2 - 4/6x - 4

Now combine -5/6x and -4/6x to get -9/6x or -3/2x

-3/2x + 51/2 - 4

Convert 4 into 8/2 since 51/2 is a fraction.

-3/2x + 51/2 - 8/2

Since the denominators of 51/2 and -8/2 are the same, just subtract 51 and 8 to get 43.

-3/2x + 43/2

-3/2x and 43/2 have the same denominator (2), so you can just put it like this (It's up to you!):

(43-3x)/2

The answer to (-5/6 + 51/2) - (2/3x + 4) is -3/2x + 43/2 (or (43-3x)/2)

Or you could put it like this (I converted both -3/2 and 43/2 to a decimal.)

-1.5x + 21.5

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

$18 was the price of the t-shirt
