Question 208930
I will set up the equation and you can finish.

Let x = height of Niagra Falls

Let (x + 750) = height of Angel Falls

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

The equation is:

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

Can you finish now?

Keep in mind that your answer must be in terms of meters.

HINT:

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