CONSTRUCTION Carlos is building a screen door. The height of the door is I foot more than twice its width. What is the width of
-BARSIC- [3]

Answer:

<h2>width = 3 feet</h2>

Step-by-step explanation:

Let h be the height of the door

and w be its width

The statement “The height of the door is I foot more than twice its width”

can be translated mathematically like this :  h = 2w + 1

Let’s solve the equation for w:

h = 2w + 1

⇔ 2w = h - 1

\Leftrightarrow w=\frac{h-1}{2}

now , if the door is 7 feet high then it’s width is equal to :

\Rightarrow \frac{7-1}{2} =\frac{6}{2} =3 \ ft
