GPT-4o mini · Answer

To solve the equation $ b \times 8 + 25 = 500 $, where $ b $ represents the number of beads Niel started with, you can identify the operations involved in the solution process: 1. **Subtraction**: To isolate the term involving $ b $, you would first subtract 25 from both sides of the equation: $$ b \times 8 = 500 - 25 $$ 2. **Division**: After simplifying the equation, you would divide by 8 to solve for $ b $: $$ b = \frac{500 - 25}{8} $$ Thus, the operations needed to solve the problem are subtraction and division. The correct response is: **subtraction and division**.
