John bought A rectangular doormat that was 1/2 a meter long and 3/10 a meter wide. suppose the doormat has a design on it that divides it into squares measuring one 1/10m by 1/10m how many squares is the doormat divided into?

Part B: What is the area of each square?

Part C: What is the area of the doormat?

Part D: Suppose another column of squares is added to the length of 1/2 meter. What is the new area?

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
