• A. -1
• B. 2
• C. 4
• D. 8

Hint:

When dealing with operations that are substituted, replace each operation in the expression according to the given instructions before simplifying step-by-step.

Answer 1

The Correct Option is B

To solve the expression \((3 - 15 \div 19) \times 8 + 6\) with the given symbol replacements, follow these steps: 1. **Replace the symbols as per the given instructions:** \begin{itemize} \item \(\times\) means \(\div\) \item \(-\) means \(\times\) \item \(\div\) means \(+\) \item \(+\) means \(-\) \end{itemize} 2. **Rewrite the expression with the new symbols:** \[ (3 \times 15 + 19) \div 8 - 6 \] 3. **Evaluate the expression step by step:** \begin{itemize} \item First, solve the multiplication inside the parentheses: \[ 3 \times 15 = 45 \] \item Then, add 19 to the result: \[ 45 + 19 = 64 \] \item Next, divide by 8: \[ 64 \div 8 = 8 \] \item Finally, subtract 6: \[ 8 - 6 = 2 \] \end{itemize} 4. **Final Answer:** \[ \boxed{2} \] Therefore, the correct option is B) 2.
