0.7 = %70 = 7/10 this needs to be 20 characters long but this is kind of an explanation
Answer: B
Step-by-step explanation: This is because C = circumfrence and R = radius
and pi is 3.14 which is the formula for finding the circumfrence of a circle
hope this helps mark me brainliest if it helped
So you want to make one of the equations equal to one of the placeholders exg y=x+3
so we have
x+y=2 and
-2x+y=2
I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x
subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0
subsitute x=0 in x+y=2
0+y=2
y=2
x=0
y=2
