Answer 1

Let x represent the number of minutes.

The guidelines state that the speech must be at least 7 minutes but not to exceed 12 minutes. This means that x must be greater than or equal to 7 minutes but x must be lesser than or equal to 12 minutes.

The representation would be

`\begin{gathered} x\text{ }\ge7\text{ } \\ x\text{ }\leq12 \\ The\text{ compound inequatity would be} \\ 7\text{ }\leq x\leq12 \end{gathered}`
