Chapter 1: Q39. (page 9)

Evaluate each expression if $w = 6, x = 0.4, y = \frac{1}{2},$ and $z = - 3$
39. $w + 12 \div z$

Short Answer

Expert verified

Expression $w + 12 \div z$ results into 2

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 6 for $w$ and $- 3$ for $z$ into given expression

$w + 12 \div z = 6 + 12 \div (- 3)$

- Simplify 6+12÷-3

Now, to simplify follow order of simplification to get

$\begin{matrix} 6 + 12 \div (- 3) = 6 + (- 4) \\ = 2 \end{matrix}$

Thus, $w + 12 \div z = 2$
