The height of a door is 1.4 feet more than 2.3 times its width. If the height of the door is 8.5 feet, which equation can be use
ladessa [460]

Answer:

2.3x+1.4=8.5, width = 3.087 feet.

Step-by-step explanation:

Let as consider width of the door be x feet.

It is given that height of a door is 1.4 feet more than 2.3 times its width. So,

Height=2.3x+1.4

The height of the door is 8.5 feet.

2.3x+1.4=8.5

Therefore, the required equation is 2.3x+1.4=8.5.

2.3x=8.5-1.4

2.3x=7.1

x=\dfrac{7.1}{2.3}

x\approx 3.087

So, the width of the door is about 3.087 feet.
