localid="1649133807572" $|50| - |x|$

Short Answer

Expert verified

The value of the expressionis 47.

Step by step solution

Step-1 – Absolute value of a number

Absolute value of any positive or negative number is always positive and equal to the magnitude of the number. The absolute value of a number N is denoted by $|N|$ .

The absolute value of a number represents the distance of the number from 0 in the number line.

Step-2 – Example of Absolute value

The absolute value of 3 is denoted by $|3|$ and is equal to 3.

And the absolute value of $- 4$ is denoted by $|- 4|$ and is equal to 4.

Step-3 – Evaluate the expression

To evaluate the value of the expression $|50| - |x|$ , substitute $- 3$ for x and simplify further as shown below,

$\begin{array}{l} |50| - |x| = |50| - |- 3| \\ = 50 - 3 \\ = 47 \end{array}$

Thus, the value of the given expression is 47.
