Chapter 1: Q5. (page 52)

Evaluate the expression when $p = 12 and q = 15$ .
5. $35 - p$

Short Answer

Expert verified

The value of $35 - p$ is 23

Step by step solution

Step 1: What is an algebraic expression?

In mathematics, a variable (usually an English alphabet) standing for an unknown value in any equation or Algebraic Expression. In general we used x, y, z or t (time), d (distance) and r for radius.

Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division).

For example, 2(x + 8y) is an algebraic expression.

Example of the variable, constant term and the coefficient

Step 3: Evaluate the expression 35 – p when p = 12

Consider, the expression provided in the question:

35 - p

To find the value of $35 - p$ when $p = 12$ , it is needed to substitute12 for $p$

The expression will be obtained as: Substitute $p = 12$

$\begin{array}{l} 35 - p \\ 35 - 12 = 23 \end{array}$ [Subtraction]

The value of $35 - p$ is 23
