(a/b)=c
first multiply both sides by b
b*(a/b)=c*b
this cancels out the b under the a
a=cb
Then divide by c
a/c=(cb)/c
this cancels the c and leaves b by itself
b=(a/c)
Answer:
A, B, D
Step-by-step explanation:
The points that lie in the overlapped area (purple), or on the blue line, are solutions to the system.
Hope that helps! :D
Just divide the arc the inscribe angle forms by 2. So 100/2 = 50 = a, and b is 55.
