Answer:

Step-by-step explanation:

Let the number be x

Four time that number = 4x

The difference between a hundred and a number = 100 -x

100- x = 4x

100 = x + 4x

100 = 5x

5x = 100

x = 100/5 = 20

Answer:

w = 33.94 ft

Step-by-step explanation:the roof takes the shape of a right angle. The top of the roof is a right angle. To find the width of the house, which is the hypotenuse of the triangular roof, we would apply pythagorean theorem.

Thus:

$w^2 = 24^2 + 24^2$

$w^2 = 1,152$

Square both sides

$\sqrt{w^2} = \sqrt{1,152}$

$w = 33.94$ (to 2 decimal places)

The width of the house = 33.94 ft
