Evaluate each expression if $a = 鈭� 2, b = 鈭� 3, c = 2$ , $x = 2.1, y = 3$ , and $z = 鈭� 4.2$ .
$|y 鈭� 2 z| 鈭� 3$

Short Answer

Expert verified

The expression $|y 鈭� 2 z| 鈭� 3$ is equal to 8.4.

Step by step solution

Step-1. Define absolute value expression.

Absolute values define an upper and lower range in which a value must lie.

Step-2. Substitute the variables.

In order to evaluate the expression $|y 鈭� 2 z| 鈭� 3$ substitute -2 for a, -3 for b, 2 for c, 2.1 for x, 3 for y and for z.

$|y 鈭� 2 z| 鈭� 3 = |3 鈭� 2 脳 (鈭� 4.2)| 鈭� 3$

Step-3. Simplify the expression.

Solve the expression as per order of operations.

$|y 鈭� 2 z| 鈭� 3 = |3 鈭� 2 脳 (鈭� 4.2)| 鈭� 3 = |3 + 8.4| 鈭� 3 = |11.4| 鈭� 3 = 11.4 鈭� 3 = 8.4$

Therefore, the value expression is 8.4.
