Question

Translate the following phrase into an algebraic expression. use the variable n to represent the number. 4 less than triple a number

Answer 1

Answer:  3n - 4

Work Shown:

n = a number, aka a placeholder for a number

3n = triple a number

3n-4 = four less than triple a number

So whatever n is, we multiply by 3 and then subtract off 4.

As an example, if n = 12, then 3n-4 = 3*12-4 = 36-4 = 32.
