Which inequality shows a value between and including 1.9 and 2.1? A. x >= 2.10 AND x 2.1

C. 1.90<= x <= 2.10

D. 2.1 <= x<= 1.9

Answers

C. $1.90\leq x \leq 2.10$

Explanation:

The question states that x has is value in between and including 1.9 and 2.1. So the number is greater than or equal to 1.9 but less than or equal to 2.1.

In option A $x\geq 2.1$ this means that the value of x is greater than or equal to 2.1 which does not satisfy the condition mentioned in the question

In option D is greater than or equal to 2.1 but less than or equal to 1.9 which does not satisfy the condition mentioned in the question.

In option C is greater than or equal to 1.9 and less than or equal to 2.1 which does satisfy the condition mentioned in the question.

So, option C is correct.
