What is the largest whole number x that satisfies 5x + 12 < 47?
Answer and explanation
Correct answer: C. 6
- Step 1: Subtract 12: 5x < 35. Step 2. Divide by 5: x < 7, so the largest whole number is 6. Answer: 6. Why not the others: 8: this value makes the left side too big. 7: this is the boundary, which is not allowed because the inequality is strict. 30: this subtracts the coefficient instead of dividing.
