1.25x + 2.5 \ \textless \ 2.75x - 6.5 \\ \\ 2.5 \ \textless \ 2.75x - 6.5 - 1.25x \ / \ subtract \ 1.25x \ both \ sides \\ \\ 2.5 \ \textless \ 1.5x - 6.5 \ / \ simplify \\ \\ 2.5 + 6.5 \ \textless \ 1.5x \ / \ add \ 6.5 \ both \ sides \\ \\ 9 \ \textless \ 1.5x \ / \ simplify \\ \\ 6 \ \textless \ x \ / \ divide \ both \ sides \ 1.5 \\ \\ x \ \textgreater \ 6 \ / \ change \ sides \\ \\ Answer: x \ \textgreater \ 6 (A)
