And you could shut up and keep your comments to yourself

Your name should be "QUEEN BOREDOM"!!

2/5x + 2 =8 subtract 2 from both sides

2/5x=8-2

2/5x=6 cross multiply

2x=30 divide both sides by 2

x=15

Or get off and do something else

tan (3°)  = (2.5) / D    where D is the distance from the bottom of the ramp to the building

Rearrange as

D  = (2.5) / tan(3°)  = about 47.7 feet

Just text someone......... 

10 ( x - 5)  = - 80        divide both sides by 10

x - 5  = - 8                 add 5 to both sides

x = -3

(4x+2)/2=x+8       multiply both sides by 2

4x + 2  =  2(x + 8)    simplify

4x + 2  = 2x + 16      subtract 2x, 2 from each side

2x  = 14      divide both sides by 2

x = 7

See you ltrs neighbor LOL

sec^2 x cos x + cos x - 2 = 0

(1/cos^2x)*cosx + cosx - 2  = 0

1/cosx + cosx  - 2  = 0       multiply through by cos x

1 + cos^2x - 2cosx  = 0     rearrange

cos^2 x - 2cos^2x + 1  =  0       factor

(cosx -1) (cosx - 1)  = 0     and since the factors are the same, we can solve for just one of them

cosx - 1   = 0      add 1 to both sides

cosx  = 1       so,   x  =    0 ± n*360°  where n is just an integer

Bye!

She had told me she was grounded, so I don't think she did suicide.

64*.75 = 48

Subtract that total from the original price.

64-48=16

The price of the bench is $16 during the sale.

Mine is great but I have to leave the website so bye everyone!!!!!!!!!!!!!!!

No problem

thanks

To elaborate, 405 / 90 = 4.5, therefore 405 is 450% of 90.  Any number divided by itself is 100%, E.G., 90 is 100% of 90.

Sorry for multiple answers, but I don't see any way to edit a response.

2*x=30

By the way, I assume what you meant to ask was "What number is 405 90% of".  If that isn't what you meant, then disregard my answer.  The literal answer to your question is "405 is 450% of 90."

Average in math ways

Reverse percentages by multiplying by 100/p%, in this case 405 * (100/90) = 450.

Simpy verified:  450 * (90/100) = 405.

Mathmatically if Y = N*(X/100) then N = Y * (100/X), where N is your original number, Y is the number after the percentage is taken, and X is the percentage expressed as a number (E.G., 90 for 90%).
