x=?
y=?

5 adult and 3 student tickets were purchased

Step-by-step explanation:

Let x  be the number of adult tickets . Then  8 − x  is the number of student  tickets .

7.25 x  + 5.5 (8 − x ) = 52.75  

7.25 x  + 44 − 5.5 x = 52.75  

1.75 x = 8.75  

x = 5

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
