Eli read four more biographies than historical fiction book during the semester. he also read two fewer mysteries than historical fiction books. if he read a total of eleven books during the semester how many of each type of books did he read?

Eli read 3 historical fiction books , 7 biographies and 1 mystery book.

Step-by-step explanation:

Let x be the number of historical fiction books Eli read.

Then, Number of biographies he read = x+4

Number of mysteries he read = x-2

If he read a total of eleven books during the semester , then we have the following equation :

 (Subtract 2 from both sides )

 (Divide both sides by 3)

Therefore , Number of historical fiction books Eli read = 3

Number of biographies he read = 3+4=7

Number of mysteries he read =3-2=1

Hence, Eli read 3 historical fiction books , 7 biographies and 1 mystery book.

the number of biographies books that Eli read is 7

the number of historical fiction books that Eli read is 3

the number of mysteries books that Eli read is 1

Step-by-step explanation:

Let x represent the number of biographies books that Eli read.

Let y represent the number of historical fiction books that Eli read.

Let z represent the number of mysteries books that Eli read.

Eli read four more biographies than historical fiction book during the semester. This means that

x = y + 4

He also read two fewer mysteries books than historical fiction books. This means that

z = y - 2

If he read a total of eleven books during the semester, it means that

x + y + z = 11 - - - - - - - - - - - - 1

Substituting x = y + 4 and z = y - 2 into equation 1, it becomes

y + 4 + y + y - 2 = 11

3y + 2 = 11

3y = 11 - 2 = 9

y = 9/3 = 3

z = y - 2 = 3 - 2 = 1

x = y + 4 = 3 + 4 = 7

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

the answer is b
