If the first angle of a triangle is x + 45, the second angle is (x + 45) - 30, and the third angle is 2x + (x + 45). What are the measurements of each angle? Remember the total of a triangle is 180.

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
