Answer:
30 hours is the right answer
The answer is approx. 10.8 per hour.
If you want to round it up, it would be 11. I prefer you not to round though as this is Money. Money should have decimals included.
Answer: 0=0 The input is an identity or it is true for all values
-3(2x+6)=-6x-18
(-3*2x)+(-3*6)=-6x-18
-6x+-18=-6x-18
0=0
L would measure at 54°. Because the angels of a triangle measure up to 180, you can set the equation up like this: 5x + 3x + 2x = 180. These are like values, so you can add them together to simplify a bit, yielding 10x = 180. Divide 180 by 10 to get x by itself, giving you 18. L = 3x, so 3(18) = 54.
