Answer 1

Kim is younger than 5 years. Kim could 1, 2, 3 or 4 years old.

Step-by-step explanation:

Let Kim's age be z.

From the question, Josh's age can be as represented below;

`Josh^(\prime)s\text{ age =}4z+6`

We're also told that the sum of their ages is less than 31, we can express this as per below;

`z+(4z+6)<31`

So let's go ahead and find Kim's age, z;

`\begin{gathered} 5z<31-6 \\ z<(25)/(5) \\ z<5 \end{gathered}`

So Kim is younger than 5 years. Kim could 1, 2, 3 0r 4 years old.
