Write a multiplication equation and a division equation that this diagram could represent. A tape diagram of three equal parts. Each part is labeled "eighteen". A brace from the beginning of the diagram to the end of the disgram is labeled "54".

Group of answer choices

3 • 18 = 54 and 54 ÷ 18 = 3

54 • 3 = 18 and 18 ÷ 3 = 54

c

3 • 18 = 54 and 54 ÷ 18 = 3

3 • 18 = 54 and 18 ÷ 54 = 3

and

Step-by-step explanation:

Given

Required

Model the scenario

The model of this scenario is:

This gives:

-- This represents the multiplication model

Divide both sides by 18

Reorder

-- This represents the division model

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.
