Question

Lamar has a bag of beads. He gives 20 beads to his sister. Then he makes 4 identical necklaces with the remaining beads. Write an expression that represents the number of beads on each necklace.

Answer 1

x/4 - 5

Explanation:

Let :

Number of beads in bag = x

Number of beads left = x - 20

Identical beads made from remaining = 4

Number of beads on each necklace :

Number of beads left / number of beads made

= (x - 20) / 4

= x/4 - 5
