shut up cuh

This is a little different to the original question......se my edited answer, here:

http://web2.0calc.com/questions/simpofly-x-1-y-x#r1

3(x-4) + 6 = 5(x-1)    simplify

3x - 12 + 6 =  5x  - 5

3x - 6  = 5x - 5        subtract 5x from both sides, add 6 to both sides

-2x  = 1                   divide both sides by -2

x = -1/2

what is math how do u use it

 (x-(1/y))/(x/y)   =

 [ (xy - 1)  / y ]   / [ x /y]  =

[ (xy - 1) / y] * [ y / x]  =

[xy - 1]  / x =

xy/x  - 1/x  =

y  - 1/x

I assume you mean that all 5 marbles are red???....if so,

We have (7/16)  chance of drawing a red marble on the first draw.......and, assuming that we draw a red one on the first draw, we have a (6/15) chance of a red one on the second draw, etc......so....the probability of all 5 being red is just :

(7/16) (6/15)(5/14)(4/13)(3/12)   = 1/208  = about .0048  =  about  0.48 %

FV=PV(1+i)^n

FV is 60000 + 33478.04    PV is 60000   i is .03     Find n

93478.04 = 60000(1.03)^n

93478.04/60000 = 1.03^n

1.55796 = 1.03^n

log 1.55796 =  n log 1.03     n= 15 years

(1) Perimeter = 2 ( L + W)     →  P  = 2(31 + 1)   =  2(32)  = 64cm 

(2) Area   = L * W    →  A  = L * W

So....we can re-arrange (1), thusly :

P = 2(L + W)     divide both sides by 2

P/2  = L + W       subtract W from both sides

P/2 - W   = L    

Substituting  this into (2), we have

A  = [ P/2 - W] * W

So.....substituting  the known values for P and W, we have

A = [ 64/2 - 1] * 1   =   [ 32 -1] * 1   = 31  cm^2

2x + y= -5        rearrage this as :   y = -2x - 5   (1)

2y  -x= 2      (2)

Now......substituting (1)  into (2),we have

2 (-2x - 5)  - x   = 2    simplify

-4x - 10   -  x   = 2

-5x - 10  = 2     add 10 to both sides

-5x  = 12          divide both sides by -5

x = -12/5

And using (1), we can find y......y = -2(-125) - 5 =   24/5  - 25/5   =  -1/5

So     ( x, y)  =  ( -12/5, -1/5)

Call the number of shirts she sold, S.  Then, her total revenue = $6 times the number of shirts she sold.

Total  (Revenue) - Total Expenses = Total Profit     ......so.....

6S   - 30   = 84      add 30 to both sides

6S = 114      divide both sides by 6

S = 19  shirts

Call the radius of the circle, r.

The area of the surrounding square, ABCD = 4r^2

The area of the square inscribed in the circle = 2r^2

The area of the circle = pi*r^2

So.....the shaded area = the area of the circle - the area of the inscribed square =  [pi*r^2 -2r^2]

So....the probability  that  a point is chosen in the shaded area  = 

shaded area  / total area bounded by ABCD =

[pi *r^2 - 2r^2] / [4r^2]  =

r^2 [ pi - 2]/ {r^2 *4]  =   [  r^2  cancels ]

[pi - 2 ] / 4        (E)

It is as "real" as you get in Math.

are all the problems by itself? or am I suppose to combine them all??

LOL! That's a very funny

As a Doctor, I'm wondering if YOUR Doctor knows what 'twerking' is  !    Hahaha

5(p-6)-2=2p-5

5p - 30 - 2 = 2p - 5

-2p              -2p

------------------------

3p - 30 - 2 = -5

3p - 32 = -5

     +32    +32

----------------------

3p= 27

p=9

:) :) :) 

5(p-6)-2=2p-5

5p - 30 - 2 = 2p - 5

-2p              -2p

------------------------

3p - 30 - 2 = -5

3p - 32 = -5

     +32    +32

----------------------

3p= 27

p=9

thanks Guest really ! I am already using that.

Solviet!!! You took my question! Ugh!

( just kidding ) :)

S circle=pi x r^2

are you asking for the formula?

FV=PV(1+i)^n  and  PV=FV(1+i)^-n    Are the SAME equations , just with the interest portion appearing on different sides.
