To write the inequality that is described in the statement we need to identify the expressions involved:
Three times m means three multiplied by a number called m:
[tex]3m[/tex]When we use the expression at least, we refer to greater than or equal to:
[tex]\ge[/tex]And 10 is just the number. Write it all together in the given order and obtain the required inequality:
[tex]3m\ge10[/tex]And that is the answer.
