RTCNTC said:In 20 years, Kayleen will be four times older than she is today. What is her current age?
Kayleen's current age is x.
Kayleen in 20 years = x + 20.
x + 20 = 4x
This equation does not make sense.
RTCNTC said:Kayleen's current age is x.
Kayleen in 20 years = x + 20.
x + 20 = 4x
20 = 4x - x
20 = 3x
20/3 = x
Kathleen's current age is 20/3. This makes no sense. I think there's a typo in the original problem.
Prove It said:Why do you think that a person can't be a fractional age? This is 6 years and 8 months...
The current age of Kayleen cannot be determined without more information. We only know that she will be four times older in 20 years.
In 20 years, Kayleen will be four times older than her current age. If we let her current age be x, then her age in 20 years will be 4x.
The equation to calculate Kayleen's current age would be x = (4x)/4. This is because in 20 years, her age will be four times older than her current age.
Based on the given information, Kayleen's current age cannot be negative. However, if we assume that her current age is a negative number, then in 20 years, she will still be four times older than her current age and the equation would still hold true.
Yes, in order to determine Kayleen's current age, we would need to know her age in 20 years or how much older she will be in 20 years. Without this information, it is impossible to calculate her current age.
