Sheila is climbing on a ladder that is attached against the side of a jungle gym wall. She is 6 feet off the
ground and is 3 feet from the base of the ladder, which is 9
feet from the wall. How high up the wall is
the top of the ladder?
The ladder is attached to the wall of the jungle gym at a height of
feet.

Given:

Sheila - 5 feet off the ground, 3 feet horizontally form the base of the ladder.

ladder - 15 feet from the wall. 

Find how high up the wall the top of the ladder is.

5 : 3 = x : 15

5*15 = 3x

75 = 3x

75/3 = 3x/3

25 = x

The top of the ladder is 25 feet high.

a negative exponent is translated as follows:

so, we have

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
