After an earthquake, $$ 3 7 of all claims were paid within a month. Of the remaining claims that had not yet been paid, $$ 2 5 of them were paid within the second month. What fraction of all claims were paid in the second month?

6/35

Step-by-step explanation:

After an earthquake, $$ 3 /7 of all claims were paid within a month.

Let the total number of claims be represented by 1

Therefore, the amount of claims that were not paid within the month is calculated as:

1 - 3/7 = 4/7

Hence, 4/7 claims were not yet paid.

Of the remaining claims that had not yet been paid, $$ 2/5 of them were paid within the second month. What fraction of all claims were paid in the second month?

This is calculated as:

2/5 of the claims that were not yet paid

= 2/5 of 4/7

= 2/5 × 4/7

= 6/35

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.
