Answer: 5 (option 3)
Step-by-step 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:
[tex]3m<30-10[/tex]
Then, the 3 that is multiplying the m goes to the other side dividing:
[tex]m<\frac{20}{3}[/tex]
Solving the division:
[tex]m<6.666[/tex]
Of these options, the only value for m that is less than 6.666 and therefore makes the inequality true is 5.
