Answer
Find out the length of the shorter and longer pieces of a board .
To prove
Let us assume that the length of the shorter pieces be x.
As given
Jared has a wooden board that is 11 ft long.
He wants to cut it into two pieces so that the longer piece is 4 ft less than 4 times the length of the shorter piece.
Than the length of the longer pieces = 4x - 4
Than the equation becomes
x + 4x - 4 = 11
5x = 11 + 4
5x = 15
x = 3 ft
Therefore the length of the shorter pieces be 3 ft .
The length of the longer pieces = 4x - 4
= 4 × 3 - 4
= 12 - 4
= 8 ft
Therefore the length of the longer pieces be 8 ft .
Answer:
Cost of new carpet per square foot should be less than or equal to $3.54.
Step-by-step explanation:
Given:
Money have to buy carpet =
dimension of game room is 20 feet by 12 feet
So we can say length l = 20 feet
and width w = 12 feet
let be the cost per square foot for new carpet.
Assuming game room to be rectangular in shape we will find the area of it.
Area of room =
Total area cost per square feet ≤ Total money we have
Hence,
Hence Cost of new carpet per square foot should be less than or equal to $3.54.
