A textbook search committee is considering 19 books for possible adoption. The committee has decided to select 7 of the 19 for f
spin [16.1K]

It can be done in 50388 ways

Step-by-step explanation:

When the selection has to be made without order, combinations are used.

The formula for combination is:

C(n,r) =\frac{n!}{r!(n-r)!}

Here

Total books = n =19

Books to be chosen = r = 7

Putting the values

C(19,7) = \frac{19!}{7!(19-7)!}\\\\=\frac{19!}{7!12!}\\\\=50388\ ways

It can be done in 50388 ways

5 + 2(3 + 2x) = x + 3(x + 1)
Free_Kalibri [48]

Answer:

no solution

Step-by-step explanation:

5 + 2(3 + 2x) = x + 3(x + 1) ← distribute parenthesis on both sides

5 + 6 + 4x = x + 3x + 3 , simplify both sides

11 + 4x = 4x + 3 ( subtract 11 from both sides )

4x = 4x - 8 ( subtract 4x from both sides )

0 = - 8 ←  false statement

This indicates the equation has no solution
