MODELING REAL LIFE The height of the house is 26 feet. What is the height x of each story?T61tThe height x of each story isfeet
lozanna [386]

The total height of the building in the picture has been shown as

x + x + 6

That is, the first two storys have been shown as x feet each and the total height is 26 feet.

That means the two x are actually 20 feet, (if you deduct the 6 feet given)

Total height = x + x + 6

26 = x + x + 6

26 = 2x + 6

Subtract 6 from both sides of the equation

26 - 6 = 2x + 6 - 6

20 = 2x

Divide both sides of the equation by 2 and you now have,

20/2 = 2x/2

10 = x

Therefore, te height of each story is 10 feet!
