To determine

To write an algebraic expression for the given verbal expression.

Answer to Problem 15CCSR

  $4x-5$

Explanation of Solution

Given:

5 less than four times a number

Calculation:

In order to write an algebraic expression for the given verbal expression, let the unknown number be x . Observe 5 is less from the four times the number.

So, the algebraic expression for the given verbal expression can be written as,

  $\begin{array}{l}\text{5 less than }\left(4\text{ times a number }x\right)\\ =\left(4\cdot x\right)-5\\ =4x-5\end{array}$

Thus, the algebraic expression for the given verbal expression is $4x-5$ .
