Answer:

220

Step-by-step explanation:

Given that the freshman class has 160 students.

Each freshman must write three reports from a list of 12 novels that the teacher has assigned them to read

Here order does not matter.  Hence combinations can be used.

No of available options  = 12

No to be selected =3

Possible number of ways = ways of selecting 3 from 12 where order does not matter

= 12C3\\=\frac{12(11)(10)}{6} \\=220

Option B is right answer.

Solve for x. 5x - 1 = 26 x = x = 5 x = -5
Doss [256]

Answer:

x = 27/5

Step-by-step explanation:

5x - 1 = 26

Add 1 to each side

5x - 1 = 26

5x-1+1 = 26+1

5x = 27

Divide each side by 5

5x/5 = 27/5

x = 27/5
