Pi has infinite amount of digits.

And it's pi day, not week.

and it was 2 days ago.

Okay so for these kind of probabilty problems you need to find out how many options are there in total.

So there are three of white, four of tan, two of blue, three of green, and four of pink.

Your total amount of options is 14.

Now you want BLUE or PINK.

Out of all of the options only six are the colors you want, so that's six out of fourteen or 6/14.

Now you just have to simplify and voilá!

Samantha has a 3/7 chance to get any shades of pink or blue.

Hope this was helpful. c:

5             64             320            40

-       x       -       =       -       =       -

8               1               8               1

Multiply 5/8 by 64/1 which gives you 320/8 which is equal to 40

OR

Take 64/8, which is 8 and multiply by 5 which is once again equal to 40

-5/2x = -7/4x - 5/6

+7/4x   +7/4x

-3/2x = -5/6

+3/2     +3/2

      x = 1.16

The probability for blue is 2/16...aka...1/8

and

The probability for pink is 4/16...aka...1/4

sqrt(200)/2 = 7.0710678118654752

Solve for x:
-5/(2 x) = -5/6-7/(4 x)

-5/(2 x) = -5/(2 x) and -5/6-7/(4 x) = -5/6-7/(4 x):
-5/(2 x) = -5/6-7/(4 x)

Bring -5/6-7/(4 x) together using the common denominator 12 x:
-5/(2 x) = (-21-10 x)/(12 x)

Cross multiply:
-60 x = 2 x (-21-10 x)

Expand out terms of the right hand side:
-60 x = -42 x-20 x^2

Add 20 x^2+42 x to both sides:
20 x^2-18 x = 0

Factor x and constant terms from the left hand side:
2 x (10 x-9) = 0

Divide both sides by 2:
x (10 x-9) = 0

Split into two equations:
x = 0 or 10 x-9 = 0

Add 9 to both sides:
x = 0 or 10 x = 9

Divide both sides by 10:
x = 0 or x = 9/10

-5/(2 x) => -5/(2 0)  =  infinity^~
-5/6-7/(4 x) => -7/(4 0)-5/6  =  infinity^~:
So this solution is incorrect

-5/(2 x) => -5/((2 9)/10)  =  -25/9
-5/6-7/(4 x) => -5/6-7/((4 9)/10)  =  -25/9:
So this solution is correct

The solution is:
Answer: |  x = 9/10

Look at my answer. 10/9 is not the correct answer.  The answer is 9/10 or 0.9.

\(\frac{-5}{2x}=\frac{-7}{4x}-\frac{5}{6}\)

\(-\frac{5}{2x}=-\frac{7}{4x}-\frac{5}{6}\)

\((-\frac{5}{2x})\times4x=(-\frac{7}{4x}-\frac{5}{6})\times4x\)

\(-\frac{20x}{2x}=(-\frac{7}{4x}-\frac{5}{6})\times4x\)

\(-\frac{20x}{2x}=-\frac{28x}{4x}-\frac{20x}{6}\)

\(-10=-\frac{28x}{4x}-\frac{20x}{6}\)

\(-10=-7-\frac{20x}{6}\)

\(-10\times6=(-7-\frac{20x}{6})\times6\)

\(-60=(-7-\frac{20x}{6})\times6\)

\(-60=-42-\frac{120x}{6}\)

\(-60=-42-20x\)

\(-60+42=-42-20x+42\)

\(-18=-42-20x+42\)

\(-18=0-20x\)

\(-18=-20x\)

\(\frac{-18}{-20}=\frac{-20x}{-20}\)

\(\frac{9}{10}=\frac{-20x}{-20}\)

\(\frac{9}{10}=\frac{1x}{1}\)  

\(\frac{9}{10}=\frac{x}{1}\)

\(\frac{9}{10}=x\)

\(0.9=x\)

6x^2 + 17x − 3   can be factored as

(6x -1) (x + 3)

And these are the dimensions in terms of length and width

-5/2x = -7/4x-5/6

Solve for x:
(-5 x)/2 = -5/6-(7 x)/4

Put each term in -5/6-(7 x)/4 over the common denominator 12: -5/6-(7 x)/4  =  (-10)/12-(21 x)/12:
(-5 x)/2 = (-10)/12-(21 x)/12

(-10)/12-(21 x)/12 = (-10-21 x)/12:
(-5 x)/2 = (-10-21 x)/12

Multiply both sides by 12:
(-5×12 x)/2 = (12 (-10-21 x))/12

12/2 = (2×6)/2 = 6:
-56 x = (12 (-10-21 x))/12

(12 (-10-21 x))/12 = 12/12×(-10-21 x) = -10-21 x:
-5×6 x = -10-21 x

6 (-5)  =  -30:
-30 x = -10-21 x

Add 21 x to both sides:
21 x-30 x = (21 x-21 x)-10

21 x-21 x = 0:
21 x-30 x = -10

21 x-30 x = -9 x:
-9 x = -10

Divide both sides of -9 x = -10 by -9:
(-9 x)/(-9) = (-10)/(-9)

(-9)/(-9) = 1:
x = (-10)/(-9)

The sign of (-10)/(-9) is positive, so (-10)/(-9)  =  1×10/9:
Answer: |  x = 10/9

x^2 + bx + 375

The positive divisors of 375 are :

1  3  5  15  25  75  125  375

So  b could equal the following for p,q   [or vice-versa]

 [375 + 1]  =  376

 [3 + 125]  =  128

 [5 + 75] =  80

 [15 + 25 ] =  40

\(0.27\)

\(\frac{27}{100}\)

\(5\frac{1}{2}\)

\(5+\frac{1}{2}\)

\(\frac{10}{2}+\frac{1}{2}\)

\(\frac{11}{2}\)

\(5.5\)

0.27= 27/100

\(log(0.001)=x\)

\(x=log(0.001)\)

\({10}^{x}=0.001\)

\(x=-3\)

Replace \(x\) with \(-3\) and solve to see if the answer is correct:

\({10}^{-3}=0.001\)

\(\frac{1}{{10}^{3}}=0.001\)

\(\frac{1}{{1000}}=0.001\)

\(0.001=0.001\)
