William says that 15 yeas from now, his age will be 3 times his age 5 years ago. if x x represents william present age, complete the following sentence
a 15 years
b 18 years
c x-15=3(x-5)
d x+15=3(x-5)

I don't know what the following sentence is:

But D is the equation to represent the situation

and A is what turns out to be his current age.

(If you want more help, on this question please post the following sentence).

Step-by-step explanation:

Let x represent the current age.

15 years from now his age is 3 times his age 5 years ago means we have the equation:

x+15=3(x-5)

(I added x to 15 because we said 15 years in the future)

Let's solve this to see if makes any sense just for fun:

Distribute:

x+15=3x-15

Add 15 on both sides:

x+30=3x

Subtract x on both sides:

   30=2x

Divide both sides by 2:

   15=x

So this means his current age is 15.

5 years ago his age would have been 10.

15 years in the future his age will be 30.

Is 30 equal to 3 times 10? Yes, it is! The equation does make sense.

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
