Question

Twice the difference of a number and 2 is at most -27

Answer 1

Explanation:

When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:

Step 1. Twice the difference of a number and 2

Let's call that unknown number as n. Then, twice the difference of a number and 2 is:

$2(n-2)$

Step 2. Twice the difference of a number and 2 is at most -27

$2(n-2)\leq -27$

So the mathematical form of the statement twice the difference of a number and 2 is at most -27 is:

$\boxed{2(n-2)\leq -27}$
