You can't directly restore the moss2007 backup to sharepoint 2010. You need to restore it back to SharePoint 2007 and then migrate it. If you have a database backup of the content database, then you could follow the steps given:

• Take the backup of the content database from the SharePoint 2007 database server.
• restore it to the database server of the 2010 environment.
• Run the cmdlet Test-SPContentDatabase –Name -WebApplication using powershell to make sure that all the required dependencies are available on the 2010 server.
• create a new web application on the 2010 server and add the content database to it. upgrade the visual look of the web application by doing to the site settings.

I hope this will help you out.
