Answer:
Given below
Step-by-step explanation:
M is Mikey and B is Betty in,
Current ages:
M= x
B= 3x (cuz she is 3 times older)
After 5 years
M= x+5
B= 3x+5 (5 years added to present age)
It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))
So,
3x+5 = 2(x+5)
3x+5 = 2x+10
3x -2x = 10-5
x = 5
Therefore,
The current ages are
Betty : 3x = 3*5 = 15
Mikey: 5 (x)
You can verify by checking with the criterias or clues given in the question.. hope this helps..mark as brainiest if this was helpful:)

<h3>How to Identify Rational Numbers?</h3>
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero
Option A) The square root of 2 is an irrational number because it cannot be given as the ratio of two integers.
Option B) π is an irrational number because you can't write it down as a non-infinite decimal. Thus this option is incorrect.
Option C) 1/3 * 9 = 3. This can be used to support her claim that product of two rational numbers is always rational because both numbers on left and right can be given as the ratio of two integers.
Option D) The square root of 3 is an irrational number because it cannot be given as the ratio of two integers.
