$c > - 12$ $c > -12$

Explanation:

If $- 84$ $-84$ is less-than $(<)$ $(<)$ $7 c$ $7c$ , then $7 c$ $7c$ must be higher in value than $- 84$ $-84$ .

So $7$ $7$ multiplied by what $= - 84$ $= -84$ ? Using a calculator, trial and error, or by dividing $- 84$ $-84$ by $7$ $7$ , you will find that

$7 \cdot (- 12) = - 84$ $7 * (-12) = -84$

So your answer is: ' $c$ $c$ is more than $- 12$ $-12$ ' OR ' $c > - 12$ $c > -12$ ' as any number higher in value than $- 12$ $-12$ could equal $c$ $c$ .

Hope this helps!
