Answer:
Width = 17.5 feet,
Length = 82.5 feet.
Step-by-step explanation:
We have been given that Darrin is hanging 200 feet of Christmas garland on the fencing that encloses his rectangular front yard. This means that perimeter of rectangular front yard is 200 feet.
We know that perimeter of rectangle is two times the sum of length and width of rectangle. We can represent this information in an equation as:
We are also told that the length is 5 feet less than 5 times the width. We can represent this information in an equation as:
Upon substituting equation (2) in equation (1), we will get:
Therefore, the width of rectangular front is 17.5 feet.
Upon substituting in equation (2), we will get:
Therefore, the length of rectangular front is 82.5 feet.
Answer:
Small gift: $2
Large gift: $7
Step-by-step explanation:
Let x represent cost of wrapping each small gift and y represent cost of wrapping each large gift.
We have been given that day one 41 small gifts were wrapped and 45 large were wrapped equaling $397.
We can represent this information in an equation as:
We are also told that day two 30 small gifts were wrapped and 47 large were wrapped equaling $389. We can represent this information in an equation as:
From equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Therefore, cost to wrap a large gift is $7.
Upon substituting in equation
, we will get:
Therefore, cost to wrap a small gift is $2.
