Final answer:
The correct answer to the student's question comparing 8 + 150 and 5 + 165 is that the former is less than the latter; hence, the inequality sign is <.
Step-by-step explanation:
To solve the problem presented in the student's question, we need to compare two expressions: 8 + 150 and 5 + 165. To do this, first, we compute the sums for each expression. The sum of the first expression is 8 + 150 = 158, and the sum of the second expression is 5 + 165 = 170. Now, we compare these two sums using an inequality symbol. Since 158 is less than 170, the correct inequality sign to use is <, which means less than.
Therefore, the answer to your question is 8 + 150 < 5 + 165.
