To solve the inequality \( Rx > 10 \) for \( x \), where \( R \) is a positive number, we can divide both sides of the inequality by \( R \). Since \( R > 0 \), the direction of the inequality remains the same.
Starting with the inequality:
\[ Rx > 10 \]
Dividing both sides by \( R \):
\[ x > \frac{10}{R} \]
Thus, the solution can be expressed as:
\[ x , > , \frac{10}{R} \]
So the answer is:
\( x > \frac{10}{R} \) over \( R \) (where \( R > 0 \)).
