She writes the equation 9𝑠=81 to solve for the length of each side of the nonagon.What should she do to solve the equation for 𝑠?HINT: In the equation, the variable s represents the length of each side of the nonagon.Subtract 9 from both sides of the equation.Add 9 to both sides of the equation.Divide each side of the equation by 9.Multiply each side of the equation by 9.
Solution
To solve the equation for , Natasha should:
Divide each side of the equation by 9.
Here are the steps:
- Start with the equation: .
- To isolate , divide both sides of the equation by 9:
- Simplify both sides:
So, the length of each side of the nonagon is 9 mm.
