Chapter 1: Q1. (page 6)

Evaluate the experssion when $x = 6 and y = 12$
localid="1647945938678" $y + 8$

Short Answer

Expert verified

The value of the expression is $20$ .

Step by step solution

Step 1. Apply the concept of addition.

Two numbers with similar signs get added and the resulting number carries the similar sign. So, if two numbers with positive signs being added, the resulting sum will be positive as well. And if two numbers with negative signs being added, then the resulting sum will be negative as well.

Step 2. Example for the addition.

If two positive numbers 2 and 3 are being added, then the resulting sum will be $2 + 3 = 5$ , which is positive as well.

And if two negative numbers $- 2$ and $- 3$ are being added, then the resulting sum will be $(- 2) + (- 3) = - 5$ , which is negative as well.

Step 3. Evaluate the expression.

To evaluate the expression $y + 8$ , substitute the value of y as 12 and add the numbers as shown below,

$\begin{array}{l} y + 8 \\ = 12 + 8 \\ = 20 \end{array}$

Thus, the value of the expression is $20$ .
