YSlow Inline Style Tags

I have a site built with the Newsflash theme. When I check it with YSlow, I am asked to minify the JS and CSS. I can take care of most of it except it looks like there are some Inline Style Tags that. Is it possible to move these to a CSS?

I believe that YSlow is complaining about:

      <style type="text/css">
    #page {
      width : 900px;
    }
    </style>
        <style type="text/css">
    body.sidebar-left #main {
      margin-left: -210px;
    }
    body.sidebars #main {
      margin-left: -210px;
    }
    body.sidebar-left #squeeze {
      margin-left: 210px;
    }
    body.sidebars #squeeze {
      margin-left: 210px;
    }
    #sidebar-left {
      width: 210px;
    }
    </style>
        <style type="text/css">
    body.sidebar-right #main {
      margin-right: -210px;
    }
    body.sidebars #main {
      margin-right: -210px;
    }
    body.sidebar-right #squeeze {
      margin-right: 210px;
    }
    body.sidebars #squeeze {
      margin-right: 210px;
    }
    #sidebar-right {
      width: 210px;
    }
    </style>
        <style type="text/css">
    body {
      font-family : Arial, Verdana, sans-serif;
    }
    </style>

Any idea where this code comes from? Can it be moved into a CSS?
