How many solutions does this equation have?

–20 − 5s = –5s + 6 − 12

No Solution

Step-by-step explanation:

-20 - 5s = -5s + 6 - 12

      + 5s   +5s

-20 = 6 - 12

-20 = -6

Both sides aren't equal to each other, so there's no solution for "s" to make both sides of the equation true.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

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
