You make an equation : x + 1/7 x = 19
combine terms : 8*x/7=19

multiply both sides by 7 :   8x = 19*7

devide both sides by 8   : x=19*7/8

solve for x :) x = 16.625

x + 1/7x = 19

8/7 x = 19

x = 19 (7/8) = 133/8  = 16 5/8

If the FIRST payment of 500 is at the end of year one, then the following equation applies:

FV= A ((  1+i)^n-1 ) / i       Results in ????     We do not have all of the information....HOW MANY YEARS???????

You are either 'B'  or NOT 'B'      if 25% are 'B'  then the rest  are NOT 'B'     100% - 25% = 75%

75% of 20 = 15 questions' answers are NOT 'B'

Let's let x = price of shirt

Then shoes = 2x

SHorts = .33x

Add them all together to eqaul the $100 he spent

x + 2x + .33x = 100

3.33 x   = 100

x = $ 30.03 = Price of Shirt

nevermind, I solved it lol

-3 + 4   =   4 -3  = 1

-n^2 +n = 0

n(-n+1) = 0       so either n= 0 or  (-n+1) = 0   or n= 1       1 and 0

1/3 (one-third)

arcsin (.8) = 53.13      or perhaps   126.86   degrees

Move from one place to another,   change from one language to another

Circumference x height = surface area    

(  Circumference = pi x d )

(-5 + -8) + (-3i +4i)

-13 + i

Set the quation = 200

200 = 250 - 5t - t^2   Subtract 200 from each side

0 = 50 - 5t- t^2         Multiply both sides by -1 (just to make it easier)

0 = t^2 + 5t - 50      Factor (or use Quadratic Formula)

0 = (t-5)(t+10)        results in t = 5  or -10   (we can't have a MINUS time value , so the only answer is t =5)

t= 5 Seconds

It's in front of your face, you just arn't looking hard enough.  In any case this is a math forum, not a crossword puzzle forum.

-15 = n/(-0.2)     Multiply both sides by -0.2

3 = n

(2x+3)(x-2)

it is like if you have the length 4, width 5, hieght 9. so you will make ( L*w+ W*H+H*L)*2

so we will make (4*5+5*9+9*4)*2

9, 10,11,12,13,14,15. the answer is 15.

Still unsolved?
