Question

Please HELP NOW!! 1. Falls Lake is another lake in North Carolina. One-fourth the

size of Falls Lake plus 100 equals the size of Lake Drummond.
Write and solve an equation to find the size of Falls Lake.

Answer 1

f = 4d -400

Explanation:

First, let's make some variables.

f = size of Falls Lake

d = size of Lake Drummond

d = (1/4)*f + 100

We can now rearrange the equation to find the size of Falls Lake.

d - 100 = (1/4)*f

4d - 400 = f

f = 4d - 400
