The correct Answer is:
To solve the problem of finding all pairs of consecutive odd integers that are both smaller than 12 and whose sum is more than 11, we can follow these steps: ### Step 1: Define the Consecutive Odd Integers Let the first consecutive odd integer be \( x \). The next consecutive odd integer can be expressed as \( x + 2 \). ### Step 2: Set Up the Inequalities We need to satisfy two conditions: 1. Both integers must be smaller than 12. 2. Their sum must be greater than 11. From the first condition, we have: - \( x < 12 \) - \( x + 2 < 12 \) From the second condition, we have: - \( x + (x + 2) > 11 \) ### Step 3: Solve the Inequalities 1. From \( x < 12 \), we directly have \( x < 12 \). 2. From \( x + 2 < 12 \): \[ x < 12 - 2 \implies x < 10 \] 3. From the sum condition \( x + (x + 2) > 11 \): \[ 2x + 2 > 11 \] Subtracting 2 from both sides: \[ 2x > 9 \] Dividing by 2: \[ x > 4.5 \] ### Step 4: Combine the Inequalities Now we combine the inequalities: - \( 4.5 < x < 10 \) Since \( x \) must be an odd integer, the possible values for \( x \) are 5, 7, and 9. ### Step 5: Find the Consecutive Odd Integer Pairs Now we can find the pairs of consecutive odd integers: - If \( x = 5 \), then the pair is \( (5, 7) \). - If \( x = 7 \), then the pair is \( (7, 9) \). - If \( x = 9 \), then the pair is \( (9, 11) \), but 11 is not less than 12. Thus, the valid pairs of consecutive odd integers that satisfy both conditions are: - \( (5, 7) \) - \( (7, 9) \) ### Final Answer The pairs of consecutive odd integers both smaller than 12 and whose sum is more than 11 are: - \( (5, 7) \) - \( (7, 9) \)
