To get X and Y by itself, move everything else to the other side of the equal sign. Do this by doing the opposite operation.
Example: x-2y=11
add 2y to both sides to get x by itself
x=2y+11
Answer:
Step-by-step explanation: it looks right to me but who knows
Both of the sides equal 2 when you divide them
Answer: 10pi
Step-by-step explanation:
C = 2(pi)r
r = 5
2*(pi)*5 = C
10pi = C is the exact answer
If we make 3.14 for the pi substitution, then:
2*3.14*5=C
31.5 = C
