If 30 people is three fifths of the club, then you can divide 30 by 3 to find out how many people make up one fifth of the club. So, 10 people make up one fifth of the club.

30 + 20 (which is two more fifths of the club) = 50 people (the entire club)

A 73 meters long stick is cut into two pieces. The longer piece is 16 meters longer than twice the length of the shorter piece.
MrMuchimi

Answer:

The longer piece: 54m

The shorter piece: 19m

Step-by-step explanation:

Make an equation from what is said.

One of the pieces is 'x'

The other piece is 2x+16

x + (2x + 16) = 73m

solve for x

x = 19

plug it in

2*19 + 16

you get 54

so 54 is the longer piece

and 19 is the shorter piece (x was the shorter piece)

Hope this helped :)
