Every time I make a question for 10 points why does it show 5 points??? Or when I make a hundred mark question why does it always make it 50 on?

those point's are given to cute boys like me

it means 5-10 points so if u put it as 10 points it will probably say 5-10

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
