C
By subtracting 18 to both sides you are separating the 3x because you are not ready to isolate the variable (x) in step 1
General Idea:
W
hen we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)
When
, then P' is enlargement of P
When 
, then P' is reduction of P
Applying the concept:
In the diagram given A'B'C' is enlargement of ABC. So the correct option will be option A. 
, enlargement
Answer:
Step-by-step explanation:
Base, b = 1/3
Height, h = 12feet = (12x 0.305)metres = 3.66m
Area of triangle= 1/2 bxh
A = 1/2 x 1/3 x 3.66
A = 0.61m^2
Or in feet's
Area of triangle = 1/2 bxh
A = 1/2 x 1/3 x 12 =2 feet^2
I think the answer is (A) 0.125 because you have a 3/24 chance of getting 3 tails in a row according to the sample space. When you simplify you should get 1/8 and when converted to a decimal 0.125. Hope this helps!
