Sally is 54 years old and her mother is 80, how many years ago was Sally’s mother three times her age?
I believe that the answer is 41 years??
M = 3s
s + 26 = m
s + 26 = 3s
26 = 2s
s = 13
54-13 = 41
Correct
Right.
To find out how many years ago Sally's mother was three times her age, we can start by setting up an equation. Let's assume that "x" represents the number of years ago.
The equation can be written as: (80 - x) = 3 * (54 - x)
Simplifying this equation, we get: 80 - x = 162 - 3x
Combining like terms, we have: 2x = 82
Dividing both sides of the equation by 2, we get: x = 41
Therefore, 41 years ago, Sally's mother was three times her age.
To find out how many years ago Sally's mother was three times her age, we can follow these steps:
1. Determine the current age difference between Sally and her mother.
Age difference = Mother's age - Sally's age
= 80 - 54
= 26 years
2. Assume X years ago, Sally's age was three times her current age. So, Sally's age X years ago would be (54 - X), and her mother's age X years ago would be (80 - X).
3. Set up an equation using the given information:
Sally's age X years ago = 3 * (Sally's mother's age X years ago).
So, (54 - X) = 3 * (80 - X)
4. Simplify the equation:
54 - X = 240 - 3X
5. Solve for X:
2X = 240 - 54
2X = 186
X = 186 / 2
X = 93
Therefore, 93 years ago, Sally's mother was three times her age. So, your answer is not 41 years but 93 years ago.
