# Thread: How High is Each Waterfall?

1. ## How High is Each Waterfall?

The upper Angel Falls, the highest waterfall on Earth, are 750 m higher than Niagra Falls. If each of the falls were 7 m lower, the upper Angel Falls would be 16 times as high as Niaga falls. How high is each waterfall?

My Work:

Let x = height of Niagra Falls
Let (x + 750) = height of Angel Falls

If each fall is reduced by 7 meters, then I know that (x - 7) represents Niagra Falls and (x + 750) - 7 represents Angel Falls.

The equation I came up with is:

(x + 750) - 7 = 16(x - 7)

Is this right?

HINT Given in Book:

The height of the Falls from the top of the Falls to the river is 188 feet (57 m).

The answer for x using the above equation is 57 meters.

Is any of this right?
