First, create 3 equations of the form ax+by+cz=d, where a, b, c, and d are constants (integers between – 5 and 5). for example, x+2y-z=-1. perform row operations on your system to obtain a row-echelon form and the solution

Scott’s bank account showed a balance of $750 on sunday. during the next five days, he made one deposit of $140 and numerous withdrawals of $180 each. let x represent the number of withdrawals that scott made. write an inequality that can be used to find the maximum number of withdrawals that scott could have made and maintain a balance of at least $100. do not use a dollar sign ($) in your response.
