Problem
The swimming pool is open when the high temperature is higher than 20^\circ\text{C}20
∘
C20, degrees, start text, C, end text. Lainey tried to swim on Monday and Thursday (which was 333 days later). The pool was open on Monday, but it was closed on Thursday. The high temperature was 30^\circ\text{C}30
∘
C30, degrees, start text, C, end text on Monday, but decreased at a constant rate in the next 333 days.
Write an inequality to determine the rate of temperature decrease in degrees Celsius per day, ddd, from Monday to Thursday.

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

answer is 144

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.
