Wow, great solution, hectictar!
1- 0.25
2-0.35
So, 0.35+0.25=.6, or 60%
I agree with Melody!
Thanks so much, CPhill! Very good, yay!
Thanks so much, CPhill!
I understood it much better now! Thanks so much, CPhill!
Thank you, CPhill! Looks delicious!
If we try 17n-1, we see that 17*1-1=16 -works
17*2-1=33 -works
17*3-1=50-works
Thus, (C) is our answer!
Lol, that's true!
We know that the sum of the angles in any quadrilateral, is 360 degrees, so \(x+5x+15+3x-25+4x-20=360, x=30, 5x+15=150+15=\boxed{165}\)
