Thank you for using the site. I'll be happy to help you with these problems.
In scanning through them, I can see where at least some of them are missing information. Can you attach the problems as a Word document or screenshots?
Since I have not received a reply from you, I'm not sure where things stand at this point. I was able to complete 11 of the 20 problems with the information that I have available to me. If you would like the solutions for those problems, please let me know.
We can work on finding a way of communicating the information for the remaining problems if you'd like.
Do you still need help on this? Please reply asap. Thanks
