Hello, I seem to be in need of some help with some homework problems. Cant seem to pinpoint why Im having so much trouble getting them done correctly. I'll post them one at a time so any help given will be easier to discuss. Thanks in advance!!!!!

Here is my work:
Hope the pics are clear. If not I can type the work up. Thanks for the help again.
