Answer:
9)x=11 y=3
11)x=18 y=5
Step-by-step explanation:
9) 9x+25=13x+19 13x-19+17y+5=180
9x+44=13x 129+17y=180
44=4x 17y=51
11=x y=3
11) 49+3x=7x-23 3x=11y-1

Answer:

Step-by-step explanation:
Circumference has the formula:
C = 2πr,
Where
C is the circumference
and
r is the radius
Given Circle Y has Circumference of 6, we can find the radius:
C = 2πr
6 = 2πr
r = 6/2π
r = 3/π
So, the radius (r_y) of Circle Y is 3/π, the first choice is right.
