Question

River C is 500 miles longer than River D. if the sim of their lengths is 5,510 miles. what is the length of each River?

River C is __

River D is __

Answer 1

Answer: River C = 3005

River D = 2505

Explanation:

River D = x

River C = (x + 500)

x + (x + 500) = 5510

2x + 500 - 500 = 5510 - 500

2x = 5010

2x/2 = 5010/2

x = 2505
