An equation and the steps to solve it are shown below:
2x − one over four (12x + 4) = 3
step 1: 2x + 3x + 1 = 3
step 2: 5x + 1 = 3
step 3: 5x + 1 − 1 = 3 − 1
step 4: 5x = 2
in which step was the error made and why?
step 1, because incorrect signs have been used
step 2, because the terms have been added incorrectly
step 3, because a number has been subtracted from both sides of the equation
no error was made

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

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
