Answer:
Angela is 12 and Micah is 28.
Step-by-step explanation:
So, the problem tells us that Micah is four more than twice Angel's age, and the sum of both their ages is 40. So, if we use a to stand for Angela's age and m to stand for Micah's age, we can safely assume our equation will look like this:
(a × 2) + 4 = m. And once that is figured out, we use a + m = 40.
For right now, we can start just randomly entering in numbers for a. Let's try 10, for example.
(10 × 2) + 4 = 24.
But does 10 + 24 = 40? No, it equals 34. So we go higher.
(12 × 2) + 4 = 28.
Does 12 + 28 = 40? Yes, yes it does.
So we can say with all certainty that Micah is 28 years old, and Angela is 12.
