35+0.9654545454545454545454545454545454

100*0.9654545454545454545454545454545454      =       96.54545454545454545454545454545454

       1*35.9654545454545454545454545454545454 =        0.9654545454545454545454545454545454

subtract      

99*0.9654545454545454545454545454545454       =     95.58

     0.9654545454545454545454545454545454       =     95.58 / 99

9558 / 9900 = 531/550

\(35.9654545454545454545454545454545454=35\frac{531}{550}\)

If you do not understand then say so!    :)

Number of terms=[common difference - first term + last term] / common difference

N =[1-14+180 / 1 = 167 terms

You sum them up as Arithmetic Series: S ={first + last} x number of terms / 2={14+180} x 167/2

=16,199

what is 2/3 of  94???     94 x 2/3 = 62.66  =~63      If only 62 members vote for the bill it will NOT pass.....you need at least 63 votes

\(\sum_{14}^{180 }\) n   = 16,199

Divide both sides of the equation by 1000 to get

50,000/x = 3.75/1000        now multiply both sides by 'x'

50,000 = x* 3.75/1000       now multiply both sides by 1000/3.75

50,000 (1000/3.75) = x

x= 13333333.333

First, square both sides of the equation to get

c^2 = a^2+b^2       now subtract a^2 from both sides

c^2 - a^2 = b^2       Now take the square root of both sides

b = +- sqrt(c^2-a^2)

Sorry Guest 3     A square yard is 9 sq feet      NOT   3 !

44*4=175+1=176

44*4=175+1=176

44*4=175+1=176

Undefined, you cannot divide by 0.

Simplify the following:
(3 - 4 i) (1 + 5 i) - (2 - i)

-(2 - i) = -2 + i:
i - 2 + (3 - 4 i) (1 + 5 i)

(3 - 4 i) (1 + 5 i) = 3×1 + 3×5 i - 4 i×1 - 4 i×5 i = 3 + 15 i - 4 i + 20 = 23 + 11 i:
-2 + i + 23 + 11 i

-2 + i + 23 + 11 i = (23 - 2) + (i + 11 i) = 21 + 12 i:
21 + 12 i

Factor 3 out of 21 + 12 i giving 3 (7 + 4 i):
Answer: 3 (7 + 4 i)

1.000.000.000.000- 542000000=  4599458000000

do you want graphic? solution? there is even a "x"?  and where?

None that I can find....   if the other two sides total 12, one has to be the hypotenuse and it must be greater than the leg 8   so 9 10 or 11  are all the values that would fit that bill   

9 the other side would be  (sqrt(81-64) ) =sqrt17

10                                               100-64 =  6

11                                                121-64 =sqrt57

so a right triangle CAN be 6 8 10      but 10+6 does not equal 12

Y=-4
X=2/3

Solve the following system:
{9 x - y = 10 | (equation 1)
-3 x - 5 y = 18 | (equation 2)
Add 1/3 × (equation 1) to equation 2:
{9 x - y = 10 | (equation 1)
0 x - (16 y)/3 = 64/3 | (equation 2)
Multiply equation 2 by 3/16:
{9 x - y = 10 | (equation 1)
0 x - y = 4 | (equation 2)
Multiply equation 2 by -1:
{9 x - y = 10 | (equation 1)
0 x+y = -4 | (equation 2)
Add equation 2 to equation 1:
{9 x+0 y = 6 | (equation 1)
0 x+y = -4 | (equation 2)
Divide equation 1 by 9:
{x+0 y = 2/3 | (equation 1)
0 x+y = -4 | (equation 2)
Collect results:
Answer: |x = 2/3           and              y = -4
