Chapter 1: Q38. (page 9)

Evaluate each expression if $w = 6, x = 0.4, y = \frac{1}{2},$ and $z = - 3$
$w + x + z$

Short Answer

Expert verified

Expression $w + x + z$ results into $3.4$

Step by step solution

- Order for simplification

To evaluate any expression involving more than one operation, follow the below order of operations:

First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
Evaluate the exponents.
Perform Multiplication and division from left to right.

Perform addition and subtraction from left to right.

- Substitute given values

Substitute $0.4$ for $x$ , 6 for $w$ and -3 for $z$ into given expression

$w + x + z = 6 + 0.4 + (- 3)$

- Simplify 6+0.4+-3

Now, to simplify add the numbers to get

$\begin{matrix} 6 + 0.4 + (- 3) = 6.4 + (- 3) \\ = 3.4 \end{matrix}$

Thus, $w + x + z = 3.4$
