Density =   mass / volume

= 40.5 g  /  15 ml   =   2.7  gm/ml

Are you sure it isn't   277 g   divided by  38 g/cm ????     that would be  277g  /  38g/cm  =  7.2895 cm

Anyway    38 g / cm   /   277g   =  .1372  cm^(-1)      or  .1372/cm

6 mos  x 5.99 / month = $ 35.94

$35.94 - $ 24.99 =  $ 10.95  savings

Density is defined   as    mass / volume

That is the plural possessive form....you don't add another 's' in the case of a word that ends in a 's'

it means  '  products's  '        Kinda like if you were referring to the possessions of someone named Dennis...

you would type    ' All of Dennis' stuff was put in boxes'     NOT  'All of Dennis's stuff was put in boxes'

I know this site is only for math, but someone might know how to do this!

this is for math so ask math only

The equation should be f - 7.5x

when f = fund and x = trips

When we substitute in the known values for f and x, the problem looks like this: 240 - 7.5(12)

First multiply: 7.5*12 = 90

Then subtract: 240 - 90 = 150

After 12 trips to the laundry, the student will have $150 left in his fund.

I'm good.

You have two different equations posted in your question....here is one

(x^8)(-x^7)  = -x^15

(9-3) / (1/3 + 1) ===  6/(1 1/3)  =  6/1  /  4/3   =    6/1 x 3/4 = 18/4 = 4 1/2

121 sqrt(3) = 121 x 1.732 = 209.578

or did you want this:

\(\sqrt[3]{121}\)  =  4.946

4/7  x  5/9  =  (4 x 5) / (9 x 7)  = 20 / 63

(x+1)^4 = 81     Take the 4th root of both side

(x+1) = +-3

x = 2 or -4

найди пропущенную букву обозначающею * при которой равенство верное (18903+783*+5621)/10+ (29*136+6396/123+60*)/100

do this

Let the points  be   (x₁, y₁)   and (x₂, y₂)........the slope, m, is given by :

[y₂ - y₁ ] / [x₂ - x₁]  = m

Example      (6,5)   and (7, 10 ) =

[ 10 - 5] / [7 - 6]  =   5/1  =  5   =  m

Note.....the order of the points doesn't matter    (7, 10) and (6,5)  =

[5 - 10] / [ 6 - 7]   =  -5/-1   =  5   = m    .......    the same result !!!!!!

{38[(1−2)−(13)2]}+14  =    work within the brackets, first

{ 38[(-1) - 26] } + 14 =

{ 38 [ -27] }  + 14 =       multiply before adding

-1026 + 14  =

- 1012

Let G be the answer we are looking for......and we have

9 + 4.50G  = 16 + 1G       subtract 1G, 9   from both sides

3.50G  = 7            divide both sides by 3.50

G  = 7/3.50   = 2

So......  2 Gigabytes equalizes the cost of both plans

1 / [ x² + 3 ]  = 0      has no solution

Notice that no matter what value we substitute for  x,  we always have a non-zero result on the left side, while the right side is always 0

Also ......multiplying each side by [ x² + 3]  produces   1  = 0........which is never true  !!!!!!
