Answer 1

Answer:

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

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;

$\begin{gathered} 5z<31-6 \\ z<\frac{25}{5} \\ z<5 \end{gathered}$

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