    First, indicate your subject in the "School Subject" box, so those with expertise in the area will respond to the question.

    Second, do not overwhelm tutors with a mass of questions.

    Third, we do not have access to the figures you refer to.

    Fourth, we do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.

    Almost all of the tutors will give you the response Ms.Sue gave you.

  • Regarding this page -

    The reason she is not giving answers is because this is a test the answers she gives is for quizzes your not allowed to have help on tests don't be upset that's why you are suppose to study before you take a test I go to a school called Texas Connections Academy. If you really need help with test take notes if your able to no need to be upset calling Ms. Sue names she has the right not to help on tests because a test shows what you learned or what you need more help understanding.
