2d = d + 11 + 11 First, write out the equation.

2d = d + 22 Then, combine like terms.

2d - d = d - d + 22 Move all the d to one side of the equation by subtracting. You MUST subtract from both sides since what you do to one side, you must do to the other.

d = 0 + 22 Here, the d - d  cancel, leaving you with 0d, or more simply, zero.

d = 22 This is your answer.

If you put it into the original equation it checks.

2d = d + 11 +11

2(22) = 22+ 11 + 11

44 = 44

2d  =  d + 11 + 11

2d  =  d + 22

d  =  22                     (subtract d from both sides)

If my interpretation is correct:  2(x² + 3y) + x + y  =  2x² + 6y + x + y  =  2x² + x + 7y 

Or, possibly:  2x(x² + 3y) + x + y   =  2x^3 + 6xy + x + y

Inverse variation has the form:  y = k / x

For this problem:  pitch = k / wavelength

                          400  =  k / 2      --->     k  = 800

Formula for this problem:  pitch  =  800 / wavelength

                                         700  =  800 / wavelength

                      700 x wavelength  =  800

                               wavelength  =  8/7 m

Here they are on a number line. Maybe it will help

Sorry, I didn't see that they could represent line segments, I thought that they represented products.

I htink that you are completely correct.

please ignore my messages

2d=?

what us the = sign supposed to be

A number made by squaring a whole number.

16 is a perfect square because 4² = 16

25 is also a perfect square because 5² = 25
etc

Remember that negative numbers behave in the "opposite" manner to positive ones...

For instance ....   3 > 2  ..... but -3 < -2

So

.7 > .07    but     -.7 < -.07

this is a legit question, Wicked

Standard Deviation is basically the average amount any number is, in a set of data, away from the mean.

Let C be the total cost....then.......

15% of C = $50     or, mathematically.....

.15C = 50              divide both sides by .15

C = 50/.15 = about $333.33

This is translated directly from Swedish and I do not know if you call it graphical solution in English but you write it with curly brackets and it would look something like:

{ y + x = 4

  y - x = -2

Wicked's answer is correct......let's see how it was derived.......

x + (x*3) = 44   is the same as

x + 3x = 44    simplify

4x = 44      divide both sides by 4

x = 11

the answer is .81

-p + q - (2p + 3q) - p - q       simplifying, we have....

-p - 2p - 3q - p  =

-2p - 2p - 3q =

-4p - 3q

and in fractions it is 2 7/10

2.7 ponds is the answer because 2.97/1.10 = 2.7

math is so important because all jobs use math.

x=11. That is the answer because 3*11=33+11=44

I dont know how to explain in more depth

??????? .....I thought this question was referring to line segments......(I don't know.....maybe other interpretations are possible.....)

tl = 14 ..... lc = 11 .......tl + lc = 14 + 11  = 25

Please ask questions that are real

2x2=4x2=8x2=16x2=32x2=64

stupid. really stewpid.
