The Zigzag River is 114 miles longer than twice the Petite River. If the Petite River is 46 miles long, how long is the Zigzag R

emmasim [6.3K]

Z = 114 + 2p
p = 46

Plug in 46 for 'p' in the first equation.

z = 114 + 2p

z = 114 + 2(46)

Multiply:

z = 114 + 92

Add:

z = 206

So the Zigzag river is 206 miles long.
