Final answer:
To evaluate the expression 6*2 - (9 / x) when x = 3, substitute x = 3 into the expression, perform the calculations step by step, and simplify the final result. Hence the correct answer is option B
Step-by-step explanation:
To evaluate the expression 6*2 - (9 / x) when x = 3:
- Substitute x = 3 into the expression: 6*2 - (9 / 3)
- Perform the division inside the parentheses: 6*2 - 3
- Multiply 6 by 2: 12 - 3
- Subtract 3 from 12: 9
Therefore, the value of the expression is 9, so the correct answer is B. 9.
