ANSWER


x\text{ }\ge\text{ 3}

Step-by-step explanation

We have that:

Six more than five times a number (x) is at least twenty-one.

That means that six times more than five times a number is greater than or equal to twenty-one.

To write this, we have that:


\begin{gathered} 6\text{ + 5x }\ge\text{ 21} \\ \text{Collect like terms:} \\ 5x\text{ }\ge\text{ 21 - 6} \\ 5x\text{ }\ge\text{ 15} \\ \text{Divide through by 5} \\ x\text{ }\ge\text{ }(15)/(5) \\ x\text{ }\ge\text{ 3} \end{gathered}

The number is 3.
