Divide 207 by 3. Add 2 to your result. Then subtract 2 from your result. Those 3 answers are what you are looking for.

Try it out on your own. Learn a little :)

you should get sixty seven, sixty nine and seventy one.

There are several mod functions.

The absolute value of imaginary (or complex) numbers are measured by their distance from zero, but on the complex plane.

The absolute value of i, is 1, so you are right.

x (shorter pipe) +2x (longer pipe) = 33 (the whole thing)

3x = 33

x = 11

the shorter pipe is 11", the longer pipe is 11"*2, which is 22"

Put 0.032 over 100.

0.032/100

To get rid of the decimal, multiply both parts by 1000.

32/100,000

Divide both parts by the greatest common factor to simplify, in this case, it happens to be 32.

1/3125

There is your final answer.

I hope this was helpful :)

Yes, both equations you've given x, y values for are linear.

How do you find out if it's linear or not? Look at the x values. 1, 2, and 3 increase by 1 each time. Their respective y values (20, 15, 10) decrease by 5 each time. If the rate of change is constant like that, the equation is linear.

If you have points like (1, 1) (2, 8) (3, 27) etc, you see that the rate of change is not constant. Each x value goes up by 1, but the second given y value increased by 7 while the next y value increased by 19, so since the rates of change are different, this equation is not linear.

I hope this helps.

m³  - m²     believe it, or not, this can be factored as a difference of two squares as  :

( m^3/2  - m) ( m^3/2 + m)

8.2%  = .082  in decimal form.....so......

.082 x 50 =  4.1

Is this an linear eguation too (1,-4)(2,0),(3,4)

yes it is

Mmmmm.....well.  OK!!!

Example

.45     write  this [ without the decimal ] over 1 plus the number of 0's  equal to the number of decimal places  = 100....so we have.....

=   45 / 100   =  9 / 20

That's it !!!

wow thanks!!

you can write it or input it as a fraction by putting in the first number and dividing by the second one.

[30 / 25   x 100]%   =

[6 / 5 x 100]%  =

[600/5] %   =

120%

What do you mean?

Im working on the same thing at school :O

Perform both multiplications, first

Then.....add the results

x component   = 12*cos(57°)

y component = 12*sin(57°)

First you can turn 3/2 into a decimal wich is 3 divided by 2 it equals 1.5 and its still negative so its -1.5 then multiply it by w wich is 6 minus 2 wich is 4 but theres a negativ so its -4 :)

There is a calculator on this site and you are using this site!

1+7u=25    subtract 1 from both sides

7u = 24     divide both sides by 7

u = 24 / 7

Let M be the miles that will equate the cost.....and we have......

17 + .07M =  22 + .05M     subtract .05M and 17 from both sides

.02M  = 5     divide both sides by  .02

5 / .02   = M = 250 miles

What you do is make the - a + because they are together so it turns into 4/5+1/5 becoming 1
