Plz asap solve simmilar triangles (basic)

By similarity of triangles we have the following relationship:

 (x) / (6) = (18) / (9)

 Simplifying we have:

 (x) / (6) = 2

 Clearing the value of x we have:

 x = 6 * 2

 X = 12

 The value of x for this case is equal to:

 X = 12

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 !
