To solve the equation [tex]\( A \div 2 = 4 \)[/tex] for [tex]\( A \)[/tex], follow these steps:
1. Start with the given equation:
[tex]\[ A \div 2 = 4 \][/tex]
2. To isolate [tex]\( A \)[/tex], you need to undo the division by 2. You can do this by multiplying both sides of the equation by 2:
[tex]\[ (A \div 2) \cdot 2 = 4 \cdot 2 \][/tex]
3. Simplify both sides of the equation:
[tex]\[ A = 8 \][/tex]
Thus, the value of [tex]\( A \)[/tex] is 8. Hence, the correct answer is:
B. 8
