I think the answer is -30 because 3* 10 is 30 and when you multiply integers with different signs you always multiply normally and give the answer a negative sign.
1) isolate k: 3(-4)>-k 2) combine like terms: -12>-k 3) get rid of the negative sign (NOTE WHEN YOU DIVIDE BY A NEGATIVE IN AN INEQUALITY YOU MUST FLIP THE SIGN): 12 ANSWER: 12
