Answer: [tex]\dfrac{b+20}{4}[/tex]
Step-by-step explanation:
Given: Liam has a bag of b beads. He gives 20 beads to his sister.
Total beads = b+20
Number of necklaces made = 4
If he uses equal amount of beads in each necklace , the number of beads in each necklace = (Total beads) ÷ (Number of necklaces made)
= [tex]\dfrac{(b+20)}{4}[/tex]
Hence, an expression that represents the number of beads on each necklace. = [tex]\dfrac{b+20}{4}[/tex]
