Question

Michelle made a bead necklace that was 14 inches long. The length of the necklace, in inches, is equal to 4 added to one-fifth the number of beads, b.

How many beads did Michelle use for her necklace?

A. 500

B. 50

C. 15

D. 25

Answer 1

Answer: B. 50

Explanation:

To solve this, we will isolate the variable b.

Given:

`(1)/(5)`b + 4 = 14

Subtract four from both sides of the equation:

`(1)/(5)`b = 10

Multiply both sides of the equation by 5:

b = 50

B. 50
