Question
**Select all possible solutions to the inequality:**  
\(5(3x - 1) < 15\)

- [ ] 13
- [ ] -1
- [ ] 2.3
- [ ] 1.3
- [ ] 12
- [ ] 43
- [ ] -2
- [ ] 4.3

**Explanation**

To solve the inequality \(5(3x - 1) < 15\), follow these steps:

1. Distribute the 5:  
   \[ 5 \times 3x - 5 \times 1 < 15 \]  
   \[ 15x - 5 < 15 \]

2. Add 5 to both sides:  
   \[ 15x < 20 \]

3. Divide by 15:  
   \[ x < \frac{20}{15} \]  
   \[ x < \frac{4}{3} \]  
   \[ x < 1.3333\ldots \]

Thus, the solutions are numbers less than approximately 1.33. Check the list of numbers to see which ones fit this criterion.
