Answer:
I think the answer should be 54 pi centimeters but I can't see all the options, area of a circle is pi r^2 so if the diameter is 18, diameter = 2r so the radius is 9. pi 9^2 is 81 pi, then the same for the 3 unshaded ones and just subtract the area of the 3 white circles (27 pi) out of 81 pi.
Step-by-step explanation:
16x -8x -12 = 24 + 20
Combine like terms:
8x-12 = 44
+12 +12
——————-
8x = 56

8 8
x = 7
Answer:
3
Step-by-step explanation:
29 = 10x - 1
+4
30 = 10x
30 divided by 10 = 3
3 = x
So Addy is 3.
I belive the answer is the 3rd one
Answer:
no solution
Step-by-step explanation:
Given
3(x - 3) = 3x , that is
3x - 9 = 3x ( add 9 to both sides )
3x = 3x + 9 ( subtract 3x from both sides )
0 = 9 ← not possible
This indicates the equation has no solution
