sineoko [7]

Answer: a) 2092278989 b) 576, c) $\dfrac{576}{2092278989}$

Step-by-step explanation:

Since we have given that

Number of students = 16

Number of desks = 16

a) How many days must pass before the class must repeat a seating arrangement?

$16!=2092278989$

If the number of rows = 4

b) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?

$4!\times 4!\\\\=24\times 24\\\\=576$

c) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?

$\dfrac{576}{2092278989}$

Hence, a) 2092278989 b) 576, c) $\dfrac{576}{2092278989}$

Enter the simplified form of the complex fraction in the box. Assume no denominator equals zero.

Olenka [21]

Answer:

$\frac{(9-x)}{3x}$

Step-by-step explanation:

we have

$\frac{\frac{2}{x-3}-\frac{3}{x}}{\frac{3}{x-3}}$

step 1

Solve the numerator of the quotient

$\frac{2}{x-3}-\frac{3}{x}=\frac{2x-3(x-3)}{(x-3)x}=\frac{2x-3x+9}{(x-3)x}=\frac{9-x}{(x-3)x}$

step 2

substitute in the original expression

$\frac{\frac{9-x}{(x-3)x}}{\frac{3}{x-3}}$

$\frac{(x-3)(9-x)}{3x(x-3)}$

step 3

simplify

$\frac{(9-x)}{3x}$
