To solve the inequality \( Rx > 10 \) for \( x \), where \( R \) is a number greater than \( 0 \), you can isolate \( x \) by dividing both sides of the inequality by \( R \):
\[ x > \frac{10}{R} \]
So, the solution to the inequality is \( x > \frac{10}{R} \).
In the context of your question, you can write it as:
\( x \ _ _ _ \ \frac{10}{R} \)
The appropriate symbol to fill in the blanks would be \( > \):
\( x > \frac{10}{R} \)
This indicates that \( x \) must be greater than \( \frac{10}{R} \).
