5.5 ? Maby?

18 =b              

lit its \(^.^)/ 

multiplying anything by 1/2 would result in half of itself. so 2 multiplied by 0.5 = 1

I know just to let you know :) i socalize to 

That dosnt mean we cant socialize, early on even admin would say a few things 

Its supposed to just be math

buhoi! 

spongebob? XD

gaben because aliens dont wear apples

nope

did that image show on anyone elses screen

-3 x 11 =  -33

The answer is 3050.

x = 110; 165; 330

405=330+75

405=165+165+75

405=110+110+110+75 

  405 : 330 = 1

 -330

    75

 405:165=2

-330

   75

 405:110=3

-330

   75

3/10 =0.3 x 100 = 30% concentration of salt.

0.8

405 mod x = 75

x = 110

x = 165

x = 330

please explain this step by step

81/91=b^(13.28)

0.890109.. = b^(13.28) take the 1/13.28th root of both roots.

b = 0.991272...

LEFT HAND SIDE:

Simplify the following:
1/(1+i)

Multiply numerator and denominator of 1/(1+i) by 1-i:
(1-i)/((1+i) (1-i))

(1+i) (1-i) = 1×1+1 (-i)+i×1+i (-i) = 1-i+i+1 = 2:
Answer: |(1-i)/2

RIGHT HAND SIDE:

Simplify the following:
1/2-(i)/(2)
1/2-(i)/2 = (1-i)/2:
Answer: |(1-i)/2

Simplify the following:
(1-sqrt(3))/(1+sqrt(3))

Multiply numerator and denominator of (1-sqrt(3))/(1+sqrt(3)) by sqrt(3)-1:
((1-sqrt(3)) (sqrt(3)-1))/((1+sqrt(3)) (sqrt(3)-1))

(1+sqrt(3)) (sqrt(3)-1) = -1+1 sqrt(3)-sqrt(3)+sqrt(3) sqrt(3) = -1+sqrt(3)-sqrt(3)+3 = 2:
((1-sqrt(3)) (sqrt(3)-1))/(2)

(1-sqrt(3)) (sqrt(3)-1) = -1+1 sqrt(3)-(-sqrt(3))-sqrt(3) sqrt(3) = -1+sqrt(3)+sqrt(3)-3 = 2 sqrt(3)-4:
(2 sqrt(3)-4)/(2)

Factor 2 out of 2 sqrt(3)-4 giving 2 (sqrt(3)-2):
(2 (sqrt(3)-2))/(2)

(2 (sqrt(3)-2))/(2) = 2/2×(sqrt(3)-2) = sqrt(3)-2:
Answer: |sqrt(3)-2
