Number of ways in which the 3 can be selected from 13 = 286
Step-by-step explanation:
Step 1:
Number of books considered by the textbook search committee = 13
Number of books selected from this 13 = 3
We need to determine number of ways in which the 3 can be selected from the 13
Step 2 :
The order of the 3 books selected does not matter. So,
Number of ways in which the 3 books can be selected from 13 books = C(13,3) = 
=
=
= 286

Answer:
x = 8
Step-by-step explanation:
Given
- 2(- 3x + 3) + 2x = 58 ← distribute and simplify left side
6x - 6 + 2x = 58
8x - 6 = 58 ( add 6 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8
