Question

Kim is 3 times as old as her cousin . The total of their ages is 36 . How old is kims cousin

Answer 1

Answer: Kim's age = 27 years

Kim's cousin age = 9 years

Step-by-step explanation:

Let Kim's age be x

And Kim's cousin age be y

Now Kim is 3 times as old as her cousin

So....

x=3 times of y

x=3y...........(1)

Now,...

Sim of there ages is 36.....

So...

x+y=36.........(2)

Putting the value of x from (1)in (2)

3y+y=36

4y=36

y=9

Sooo Kim's cousin age in 9 years and putting it in equation (2)we get

Kim's age =27 years

Hope it help

Answer 2

Answer:

so,we will multiply 3×36=108 ÷3=36

Step-by-step explanation:

so,let him age be y so 3y+y=36

so we have to find that number that is Y so why is equal to KIMS cousin age show the process of finding y is this

36=3y+y

2y=36÷3

2y=12

now we have to find y

y =12÷2

y=6

checking

as we know that the sum of KIMS age and cousins age is 36 and kids age =6 and

3 times of 6=6×3=18 and 18 +6=24

hence, it's the correct answer yarra is answer ko karne my ada ghanta laga hai kabhi me 6 class me hoon agar accha laga to plz brainliest mark karde
