Final answer:
The inequality that represents the sentence 'Five plus four is less than ten plus two' is 5 + 4 < 10 + 2.
Step-by-step explanation:
The inequality that represents the sentence 'Five plus four is less than ten plus two' is:
5 + 4 < 10 + 2
To determine the correct inequality symbol, we need to evaluate both sides of the equation. On the left side, 5 + 4 equals 9. On the right side, 10 + 2 equals 12. Since 9 is less than 12, we use the less than symbol (<) to represent the relationship between the two sides.
