Consider this set of fractions. 2/3 , negative 2/3, 1, -1, 1/3, negative 1/3 explain the order and placement of these numbers on a number line.

Summarizing, we place the fractions provided in this order from left to right:

-1 < -2/3 < - 1/3 < 1/3 < 2/3 < 1

or in order from right to left on the number line:

1 > 2/3 > 1/3 > -1/3 > -2/3 > -1

Step-by-step explanation:

1. Let's place the set of fraction numbers given on a number line. We'll place the lowest on the extreme left and we'll continue to place the rest until we place the highest on the extreme right, this way:

On the extreme left:

Negative 1 (It is the lowest number)

The next one from the left to right is:

Negative 2/3

- 2/3 > - 1

The next one, to the right of - 2/3 is:

Negative 1/3

- 1/3 > - 2/3

The fourth from left to right is:

1/3

Positive numbers are always bigger than negative numbers and 1/3 is the lowest positive number we have in this set.

The fifth from left to right is:

2/3

Finally, the highest number in this set and in the extreme right of the number lines is;

1

Summarizing, we place the fractions provided in this order from left to right:

-1 < -2/3 < - 1/3 < 1/3 < 2/3 < 1

or in order from right to left on the number line:

1 > 2/3 > 1/3 > -1/3 > -2/3 > -1

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.
