Question

Find a solution to the inequality. X>7
A.5
B.9
C.1
D.7

Answer 1

The answer is B. 9.

Step-by-step explanation:

So the verbal statement of this inequality is: "X is greater than 7."

Since we know that 5 and 1 are lesser than 7, those two numbers couldn't replace X and make the statement true.

With 7, some people often get caught up and think that 7 can fit this statement. However, 7 is not greater than 7 but equal to 7. Since the inequality symbol is > (greater than) and not ≥ (greater than or equal to), 7 cannot replace X and make the statement true.

Lastly, since we know that 9 is greater than 7, 9 could replace X and make the statement true; hence, making it the final answer.
