Question

Write an algebraic expression for 12 less than a number times 7

Answer 1

Answer: 7*N - 12

Explanation:

Let's break this so is easier to interpret.

"12 less than a number"

if we call the number as N, this is written as:

N - 12

and the complete sentence is:

"12 less than a number times 7"

So we must multiply our number, N, by 7.

Then the expression is:

7*N - 12
