Answer: 5 (option 3)
Explanation:
To solve the inequality you have to isolate the variable m, so the first step is to move the 10 to the other side of the inequality, changing its sign:
![3m<30-10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mzcfy8gibonxk6ir21phaj0v8rcex5qxkv.png)
Then, the 3 that is multiplying the m goes to the other side dividing:
![m<(20)/(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2y78urbt9xim94idebjx58kz35hhy5hpiw.png)
Solving the division:
![m<6.666](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9tpmyugwgo7a3v8q3q1u953f6mk8f3ai3r.png)
Of these options, the only value for m that is less than 6.666 and therefore makes the inequality true is 5.
