Answer 2

Answer:

5

Step-by-step explanation:

Think of a number, double it, add ten, divide it in half, and subtract the number you started with. The answer is five. Why?

Think of a number,

Okay, my number is N

double it,

My number is now 2N

add ten,

My number is now 2N + 10

divide it by two, (multiply by ½),

My number is now 2N2+102 = N + 5

We just UNDID the “double it” from above.

(times two divided by two equals one)

and subtract the number you started with.

My number is now N + 5 – N or just plain 5

We just UNDID the starting number

(plus N minus N equals zero)

The answer is five. Why?

As you can see by looking at each of the steps above, the only steps that we did not UNDO were

add ten, which when divided by two, gives us our ending number
