Write and solve an equation for the following. Four more than one-half a number is three. What is the number?

4+ x = 3

Step-by-step explanation:

4 + x = 3 (subtract 4 from both sides)

x = -1 (multiply both sides by 2)

x = -2

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

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
