Question

Translate this phrase into an algebraic expression.

Four less than the product of 19 and a number

Use the variable n to represent the unknown number.

Answer 1

(n*19)-4

Explanation:

A product is the result of multiplication, so the product of a number (represented as n) and 19 would be n*19. Put these in parentheses, so that it remains organized and you don't become confused later.

Then 4 less would simply mean you subtract 4 from the product of n and 19.

(n*19)-4

Answer 2

4 <19n

Explanation:

Four less than the product of 19 and a number

n to represent the unknown number.

n represents the unknown number

Product means multiplication

Product of 19 and a number means multiply 19 and a number

We know the unknown number is 'n'

so the product of 19 and a number is 19 * n

For less than we use < symbol

Four less than the product of 19 and a number

4 < 19*n

or 4 <19n
