Steps to Solve:
~Multiply 3 to both sides
d/3 * 3 - 10 * 3 = -2 * 3
~Simplify
d - 30 = -6
~Add -30 to both sides
d - 30 + -30 = -6 + 30
~Simplify
d = 24

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
Step 3 :
Answer :
Number of ways in which the 3 can be selected from 13 = 286
