Chapter 1: Q59. (page 36)

Evaluate the expression when $x = 6 and y = 12$ . (Lesson 1.3)
localid="1649147546197" $\frac{x + y}{3}$

Short Answer

Expert verified

The value of the expression is6.

Step by step solution

Step-1 – Order of operations

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.

Step-2 – Evaluate expression inside grouping symbol

To evaluate the expression $\frac{x + y}{3}$ , substitute 6 for x and 12 for y in the given expression and simplify the expression on numerator as follows

$\begin{matrix} \frac{x + y}{3} = \frac{6 + 12}{3} \\ = \frac{18}{3} \end{matrix}$

Step-3 – Divide the numbers

Now to simplify further, divide the numbers to get

$\begin{matrix} \frac{x + y}{3} = \frac{18}{3} \\ = 6 \end{matrix}$

Thus, the value of the expression is 6.
