At east high school each of 45 classroms has an average of 22 students. at west school each of the 42 classrooms has an average of 23 students. how many more students are at east school than at west school

Since you derive the answer based on an average, the answer will not be specific but also an average

School 1: 45 classrooms x 22 students

School 2: 42 classrooms x 23 students

School 1 = 990     School 2 = 966

There is a difference of 24

step-by-step explanation:

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.
