Question

Think of a number 0-9. Double it. Add 10. Divide it by 2. Subtract your result by your original number. Are you left with 5?

Answer 1

Answer:

$\text{Yes you are left with 5 eventually.}$

Step-by-step explanation:

$\text{Let }x\text{ be a number between 0 - 9.}\\\text{After doubling, the number}=2x\\\text{After adding ten, it becomes = }2x+10\\\\\text{Dividing this number by 2, }\dfrac{2x+10}{2}=x+5\\\text{Now we subtract the original number from here, }\\x+5-x=5$

$\text{In fact, }x\text{ can be any finite number, not just from 0-9.}$

Answer 2

Answer:

Yes

Step-by-step explanation:

This is one of those number tricks that always end up with one specific number! When given the variable set 0-9, the input is x, and the output is always 5.
