Question

what is the absolute value of 9.9? 9.9 -99 99 10

Explanation:

Step1: Recall absolute value definition

The absolute value of a number \( x \), denoted \( |x| \), is the distance of \( x \) from 0 on the number line. For a non - negative number \( a \) (where \( a\geq0 \)), \( |a| = a \).

Step2: Apply the definition to 9.9

Since \( 9.9\) is a non - negative number (it is greater than 0), by the definition of absolute value, \( |9.9|=9.9 \).

Answer:

9.9
