An object that weighs 50 newtons on Earth weighs approximately 20 newtons on the planet Mercury. A rock weighs 100 newtons on Earth. What is the approximate weight of the rock, in newtons, on Mercury? 40

70

170

250

It would weight 40 newtons

Step-by-step explanation:

because something that ways 50 newtons here weighs 20 newtons on Mecury so all you do to find out how many newtons a 100 newton object weighs on Mercury multiply it by 2

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.
