Question

Evaluate the expression when$p=12 \text{and} q=15$.

5. $35-p$

Short answer

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
