Question

Question Niel has a bucket of beads. He uses them to make 8 identical necklaces and then buys 25 beads at the store. He ends up with a total of 500 beads. How many did he start with? Identify the operations needed to solve this problem using the equation b8 + 25 = 500 .(1 point) Responses addition and division addition and division addition and multiplication addition and multiplication subtraction and division subtraction and division subtraction and multiplication

Answer 1

To solve the problem using the equation \( b \times 8 + 25 = 500 \), we first need to isolate the variable \( b \).

Here’s how the operations break down:

1. Subtract 25 from both sides: This operation is necessary to account for the beads Niel bought after making the necklaces.

   \[ b \times 8 = 500 - 25 \]

2. Division: After calculating \( 500 - 25 \), we will divide by 8 to find the number of beads he started with.

Thus, the operations needed are subtraction and division.

Therefore, the correct response is subtraction and division.
