9 stacks of cards and 4 cards left over because when you divide 85 by 9 you get 9.4. So you'd multiply just 9 to get 81 and 4 cards leftover

10-12 please help, find the missing number and once you found the missing number and answered it you make sure it’s the solution
irinina [24]

10. Infinitely many solutions:

2(x-1)+6x=4(?-1)+2.

Simplify this equation:

2x-2+6x=4\cdot ?-4+2,\\ \\8x-2=4\cdot ? -2,\\ \\8x=4\cdot ?

When ?=2x, the equation becomes

8x=8x \text{ or } 0=0.

This equality is true for all x, thus the equation has infinitely many solutions.

11. The equation 5x-(x-2)=2x-(?) should have one solution x=-1.

First, simplify the equation:

5x-x+2=2x-?,\\ \\4x+2=2x-?,\\ \\2x+2=-?,\\ \\?=-2x-2.

This equation will have solution x=-1 when

?=-2\cdot (-1)-2=2-2=0.

Therefore, the initial equation is

5x-(x-2)=2x.

12. The equation -(x-8)+4x=2\cdot ?+x should have infinitely many solutions.

Simplify it:

-x+8+4x=2\cdot ?+x,\\ \\2x+8=2\cdot ?,\\ \\2(x+4)=2\cdot ?.

When ?=x+4, this equation will have infinitely many solutions.

How do you simplify(n!)^2/(n+1)!(n-1)!
ANTONII [103]
We haven n! = (n-1)! x n and (n+1)! = n! x (n + 1);
Then, (n!)^2 = n! x n! = n! x (n-1)! x n;
And (n+1)!(n-1)! = n! x (n + 1) x (n-1)!;
Finally, [n! x (n-1)! x n] / [n! x (n + 1) x (n-1)!] = (n+1)/n;

volume = \pi \times  {r}^{2} \times h \\ volume = 3.142 \times (10 \div 2)^{2} \times 18 \\ volume \:  = 3.142 \times 25 \times 18 \\ volume = 1413.9{cm}^{3}

price =  \frac{1413.9 \times 0.02}{10}  = 2.8278 = 2.83 \: dollars
