Question

Which number sentence is not true?O A) |-20| < 20OB) |9| = 9OC) |-20| > |9|>OD) |9| < |20|

Answer 1

The modulus gives the absolute value of the number (without the sign). That is

`\begin{gathered} |-a|=a \\ |a|=a \end{gathered}`

So, let's evaluate each sentence.

A) |-20| < 20

20 < 20

FALSE

The right statement would be 20 = 20

B) |9| = 9

9 = 9

TRUE

C) |-20| > |9|

20 > 9

TRUE

D) |9| < |20|

9 < 20

TRUE

Answer: Sentence A is not true.
