Where is your question?! please dont post pictures.
Unfortunately you have not included the directions. Are you supposed to solve for x? or for y?
Suppose the directions say, "Solve for x." Then, clear out the decimal fraction by mult. both sides of the given equation by 10. This will give you the solution, that is, a formula for x in terms of y.
all of them???

Answer:
As shown in picture,
volume of cone V = base area x height x (1/3) = pi x (4/2)^2 x 6 x (1/3) = 8 x pi
volume of cup V = base area x height = pi x (3/2)^2 x 3 = 6.75 x pi
(all the volumes are in cubic inches)
A - Incorrect
24 pack of cups: V = 24 x 6.75 x pi = 162 x pi
21 pack of cones: V = 21 x 8 x pi = 168 x pi
162 x pi < 168 x pi
B - Correct
12 pack of cups: V = 12 x 6.75 x pi = 254.5 > 250
C - Correct
14 pack of cones: V = 14 x 8 x pi =351.9 > 350
D - Correct
Volume of cylinder 8 tall, 6 wide: V = pi x (6/2)^2 x 8 = 72 x pi
12 pack of cups: V = 12 x 6.75 x pi = 80.4 x pi > 72 x pi
Hope this helps!
