Question

The perimeter of a rectangular wooden deck is 90 feet. The deck's length, I, is 5 feet less than 4 times its width, w. Which System of linear equations can be used to determine the dimensions, n feet, of the wooden deck?

Answer 1

Answer:

Step-by-step explanation:

let width is equal to x then length is equal to 4x-5

linear pair that can be used

2(4x-5+x)=90 feet

2(5x-5)=90feet

10x-10=90 feet

Answer 2

System of linear equations can be used to determine the dimensions, n feet, of the wooden deck:

$l = 4w-5$

$10w-10=90$

Step-by-step explanation:

Let the width be w

We are given that The deck's length, I, is 5 feet less than 4 times its width, w.

So, Length of deck = 4w-5

So,$l = 4w-5$

Perimeter of rectangular wooden deck = $2(l+b)=2(4w-5+w)=2(5w-5)=10w-10$

We are given that The perimeter of a rectangular wooden deck is 90 feet.

So,$10w-10=90$

So, System of linear equations can be used to determine the dimensions, n feet, of the wooden deck:

$l = 4w-5$

$10w-10=90$
