x is in the overlap of B and C, but not A. So
x ∈ B ∪ C
x ∈ B ∩ C
are the only correct choices.
60/30 as a mixed # is 2/1 or 2
Mikel carried the ball 4 1/2 yards. Let’s convert this: 9/2 yards (4*2+1), and if Fred carried it twice as far, that means he carried it 2 times 9/2. We know that 9/2 (or 4.5) * 2 is 9, so he carried it 9 yards.
Cross multiply
10(x-3) = 9x
10x - 30 = 9x
-1x = -30
X = 30
Area is pi•r^2
pi•r^2 = 36pi
r^2 =36
r = ?
