Question

Drag the tiles to the correct boxes to complete the palrs. Match each expression to Its simplified form. (6r+7)+(13+7) (13 - -) - (1 - .) (-8-~)+(21-4) (71 - 2) - ( + 6r)

Answer 1

`\mleft(6r+7\mright)+\mleft(13+7r\mright)=​13r+20`
`\begin{gathered} (13-(3)/(2)r)-(1-r) \\ =13-(3)/(2)r-1+r \\ =12-(3)/(2)r+r \\ =12-(1)/(2)r \end{gathered}`
`\begin{gathered} (-8-r)+(2r-4) \\ =-8-r+2r-4 \\ =-12+r \end{gathered}`
`\begin{gathered} (7r-(3)/(2))-((2)/(3)+6r) \\ =7r-(3)/(2)-(2)/(3)-6r \\ =r-(13)/(6) \end{gathered}`
