To solve for \( x \) in the equation \( 4x9 = 18 \), we should first reinterpret the equation correctly. The exponent notation typically confused here should actually clarify as multiplication because \( 4x9 \) might suggest \( 4 \times 9 \).
So instead:
\[ 4 \cdot x \cdot 9 = 18 \]
To isolate \( x \), we should first combine the coefficients:
\[ 36x = 18 \]
Next, divide both sides by 36 to solve for \( x \):
\[ x = \frac{18}{36} \]
\[ x = \frac{1}{2} \]
\[ x = 0.5 \]
Thus, the correct answer is \( \boxed{0.5} \), but this isn't listed among the given multiple-choice options. There may be an error in the problem statement itself or the provided choices.
