13x + 7 = 5x - 20  subtract 5x, 7  from both sides

8x  = - 27      divide by  8

x  = - 27 / 8

(4.22*10^15)^2 = 17808400000000000000000000000000

Or 1.78084 * 10^31

[12 + 1/2 ] - [ 7 + 2/5 ]  =

25/2 - 37/5        common den.   = 10

[25 * 5] / 10  -  [37 * 2] / 10  =

125 / 10  -  74 / 10  =

51 /10

Riddle me this...do you think I care

12 2/3

Good deal ...!!!

1 in  = 10 yds

12 in    must be 12 times as long  =   120 yds

Thanks CPhill! Was having a hard time, but I understand it now. 

(x+7)^3=1000    take the cube root of both sides

[(x +7)^3]^(1/3)  = 1000^(1/3)

x + 7  = 10     →   x  = 3

I'm going to say Julie becuase no one else has.

2*(1/3)^(0.3-x)-4=2  add 4 to both sides

2*(1/3)^(0.3-x) = 6     divide both sides by 2

(1/3)^(.3 - x)  = 3      

Note......  (1/3)^(.3 - x)  = 1 / [ 3^(.3 - x)] =   3^[ - ( .3 - x)]   = 3^(x - .3)

3^(x - .3)  = 3^1        equate exponents

x - .3  = 1     add .3 to both sides

x  = 1.3

was it gerry

YES

whats wrong with you

that is very innapropriate you should be kicked off the website

nooooooooooooooooooooooooooooooooo

that is not really nice

d**n boy nice byut whats wrong with you

I think it is Jason and Sophie

nope

LCM 4 ,14

4  = 2^2

14 = 2    *  7

Take the product of each unique factor along with its highest power....so....

2^2  * 7   =

4 * 7  =

28

u^(-7t) * u^3  =    u^3 / u^(7t)

b+3=2b-1     add 1 to both sides, subtract b from both sides

4  = b
