The school field trip for December is to the local Holiday Festival where there are horse drawn carriage and sleigh rides. Every student gets to take the horse drawn carriage or the sleigh ride. In the first hour 4 horse drawn carriage rides and 5 sleigh rides took a total of 132 students. In the second hour 6 horse drawn carriage rides and 4 sleigh rides took a total of 156 students. If the same number of students rode on each horse drawn carriage ride and the same number of students rode on each sleigh ride, how many students rode on each horse drawn carriage ride? How many students rode on each sleigh ride?

step-by-step :

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.

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
