To solve the inequality \( 5.14x + 2.25 > 15.1 \), we can follow these steps:
- Subtract \( 2.25 \) from both sides:
\[ 5.14x > 15.1 - 2.25 \]
- Calculate \( 15.1 - 2.25 \):
\[ 15.1 - 2.25 = 12.85 \]
- Now the inequality is:
\[ 5.14x > 12.85 \]
- Next, divide both sides by \( 5.14 \):
\[ x > \frac{12.85}{5.14} \]
- Calculate \( \frac{12.85}{5.14} \):
\[ \frac{12.85}{5.14} \approx 2.5 \]
- So, the inequality can be written as:
\[ x > 2.5 \]
Now, to write it with \( x \) first:
\[ x > 2.5 \]
The answer in decimal form to the tenths place is:
\[ \boxed{2.5} \]
