Fiona is mixing fertilize with peat moss to add to her garden. The amount of fertilize is proportional to the amount of peat moss. Fiona adds 2/4 pounds of fertilizer for every 8 pounds of peat moss. What is the constant of proportionality for the relationship between the weight of the fertilizer and the weight of the peat moss? -Make a table -Select unit rate -show division pounds of peat moss per pound of fertilizer. -divide (KCF)

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:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

multiple all that
