A farmer wants to build a small, rectangular pen next to a barn. She has 55 feet of fence available and needs the length of the pen to be three times the
width. If the barn forms the fourth side of the pen as shown in the figure
below, what dimensions (length and width) should the pen be so that all 55 feet
of fence are used with the other three sides? *You must use a variable to
write an equation, show your work, and label your correct answers with the
correct units for full credit.
Equation: _

Width _

Length _

Units for both width and length _

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 !

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
