Answer 5

you take the first letter L=50
and add x =10
and then there is another x which means add another 10 but since there is an I in front that means you subtract 1 from 10 =9
so you have 50+10+9

Answer 6

as long as the roman numerals are in descending order you add one digit after another
but if there is a raman numeral of lesser value than the one that follows it you have to subtracts its value from the numeral that follows
hence subtracting the 1 from 10 because the I is in front of the 10
