The difference of twice a number and 2 is at least −26. use the variable for the unknown number. translate this sentence into an inequality.

2 (c-2) ≤ -26

Step-by-step explanation:

Let's look at the phrase "Twice the difference of a number and 8".

We're using c for the unknown number.

So "the difference of a number and 8" is written −c8.  

Taking twice this quantity, we get 2−c8.

The symbol for "is at most" is ≤. We get the following:

2 (c-2) ≤ -26
