Question

Sarah made a necklace using 5 times as many blue beads as white beads.She used a total of 30 beads .How many blue beads did sarah use?

Answer 1

25

Explanation:

Let the number of white beads be w.

Then the number of blue beads is 5w since it is 5 times greater.

Total number of beads = number of white beads + number of blue beads = w + 5w

Total number of beads = 30

5w + w = 30

6w = 30

w = 5

number of blue beads = 5w = 5(5) = 25
