In the diagram below of triangle QRS, T is a midpoint of QR and U is a midpoint of RS. If TU = 80 – 8x, and QS = 104 – 9x, what is the
measure of TU?

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books
