![diskutil list ](https://i.stack.imgur.com/IABh3.jpg)

I basically tried to partition my 500GB hard drive to 350GB/150 GB ratio to install windows 10. However since the Bootcamp assistant could not download the windows support files it had to roll back. However, it’s been an hour since the process started and so I quit the BCA. I’ve uploaded a picture of the list of diskutil list and I have no idea what’s going on. 

I’d highly appreciate it if one of you experts can show me how I can merge them back into Macintosh HD as a single 500GB volume. 

Thanks in advance !
