Question

Match each equation to one of the two tape diagrams. Dragon drop each card to match the equation to the correct tape diagram. - (please use ss)

Answer 1

First diagram:

Sum of the three parts is equal to 9: x+x+x is 9 or three times x is 9

Equations:

`\begin{gathered} 3\cdot x=9 \\ 9=3\cdot x \\ x+x+x=9 \end{gathered}`

Also you can write the equation 3*x=9 as follow by solving x:

`x=9/3`

Second diagram:

Sum of the two parts is equal to 9: x+3 = 9

Equations:

`\begin{gathered} x+3=9 \\ 3+x=9 \end{gathered}`

Solving x you can write the equation:

`x=9-3`
