n = 5
Hello,
sin² x-cos² x=sin² x-(1-sin² x)=2sin² x-1
==============================
4/10 the second one is 6/10 why because the number line goes by tens so ten is always under the fraction of the number line
Set up a proportion
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64
So there are 64 notes in the bag
