Dylan is 9 years older than parry. together their ages sum to 65 years. how old is parry?
a. 28
b. 37
c. 56
d. 45

Ur answer would be C cuz 56+9 = 65!

hope i helped!

When figuring out this type of question, we work backwards.

So, let's say that d= Dylan's age, p= Parry's age and s= the sum of their ages.

So d= p+9 and p+d=65.

When we write this as an expression, we get p + (p+9) =65.

We need to work out what p is!

First, let's take away 9 from 65. We get 56.

Now we know that Dylan and Parry's age is 56 divided by 2, because there are two of them. We know this because Dylan is 9 years older than Parry, and when we minus this 9, their ages are equal!

So, now it is a simple matter of dividing 56 by 2. This equals 28! Is this Parry's age?

To be sure, let's subsititue the factors we found into our equation: p + (p+9) =65.

So, 28 + (28+9) =56

To simplify, 28 + 37 = 65.

Everything checks out! Parry's age is 28 years!
