To solve the inequality \(5x + 12.5 < 23.1\), you can follow these steps:
Step 1: Subtract 12.5 from both sides.
\[5x + 12.5 - 12.5 < 23.1 - 12.5\]
This simplifies to:
\[5x < 10.6\]
Step 2: Divide both sides by 5.
\[\frac{5x}{5} < \frac{10.6}{5}\]
This simplifies to:
\[x < 2.12\]
Now for the answers to the questions:
-
Step 1: Subtract 12.5 from both sides.
-
Step 2: Divide by 5.
-
Question 2: The solution in decimal form to the hundredths place is \(x < 2.12\).
