Differentiate using the exponential rule, which determines that is
when a=3.
Therefore, the correct option is "E". You just have to remove the parentheses.
Leo is three times older than mark. If the sum of their age is 32, how old is Leo
1 answer:
Answer: Leo is 24 years old,
Step-by-step explanation:
Let 'x' denotes the age of Mark.
Given , Leo is three times older than Mark.
i.e. Expression for Leo's age =
Since , sum of their age is 32, then
Now , divide both sides by 4 to get the value of x.
Thus , Age of Mark = 8 years
Age of Leo = 3 (8) = 24 years
Therefore , Leo is 24 years old.
