Please help thank you and explain please

x = 48

Step-by-step explanation:

first you would add them together and set it equal to 180( because a straight line is 180 degrees): 3x - 12 + x = 180

Then you add like terms( the x's): 4x - 12 = 180

now add 12 to both sides: 4x = 192

now divide by 4 on both sides x = 48

hope this helps! : )

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 !

true? is that what you're asking or do you mean something else?
