Let's solve each of the inequalities to find out which one includes the numbers 12, 13, and 14 in its solution set.
1. **Inequality: \( 2x < 13 + 15 \)**
Simplifying gives:
\( 2x < 28 \)
Dividing by 2:
\( x < 14 \)
This includes the solutions 12, 13, and 14 (since it is less than 14).
2. **Inequality: \( 2x ≤ 12 \)**
Dividing by 2 gives:
\( x ≤ 6 \)
This does not include 12, 13, or 14.
3. **Inequality: \( 2x ≥ 34 - 6 \)**
Simplifying gives:
\( 2x ≥ 28 \)
Dividing by 2:
\( x ≥ 14 \)
This includes 14 but not 12 or 13.
4. **Inequality: \( 2x ≥ 11 + 13 \)**
Simplifying gives:
\( 2x ≥ 24 \)
Dividing by 2:
\( x ≥ 12 \)
This includes 12, 13, and 14.
Now, looking at the solutions:
- The first inequality \( x < 14 \) includes 12 and 13 but not 14.
- The second inequality \( x ≤ 6 \) does not include any of 12, 13, or 14.
- The third inequality \( x ≥ 14 \) includes only 14.
- The fourth inequality \( x ≥ 12 \) includes 12, 13, and 14.
Thus, the correct answer is the fourth inequality: **\( 2x ≥ 11 + 13 \)**.
