Answer:

c=357

Step-by-step explanation:

3220=9c=7

Move variable to the left-hand side and change its sign

-9c+3220=7

Move constant to the right-hand side and change its sign

-9c=7-3220

Calculate the difference

-9c=-3213

Divide both sides of the equation by -9

c=357

How do I convert radians to degrees? Is it pi/180 or 180/pi? I get them confused! Thanks
o-na [289]
It could be either one, depending on whether you intend to multiply or divide.

When you convert, just remember that degrees ==> less radians,
and radians ==> more degrees.  Then you can always check the
results, and make sure that you used the right conversion factor
in the right direction.

3000cm because if you look at the variables there is no more letter m's than anything so if you cancel out and see what is equal to 30 then you get 3000cm!!!!!
