Regan's grandfather has a very old pet tortoise. He told Regan that the tortoise was 48 years old when she was born 12 years ago. Regan is amazed and wants to know how old the tortoise is now.
Which equation can Regan use to find the tortoise's age t?
Solve this equation for t to find the tortoise's age.
The equation Regan can use to find the tortoise's age is:
t = 48 + 12
Simplifying, we have:
t = 60
Therefore, the tortoise is currently 60 years old.
To find the tortoise's age, Regan can use the equation:
t = 48 + 12
This equation represents the tortoise's age when Regan was born, which is 48 years, plus the time that has passed since Regan was born, which is now 12 years.
Simplifying the equation, Regan can find the tortoise's age:
t = 60
Therefore, the tortoise is 60 years old now.
To find the tortoise's current age, Regan can use the equation:
t + 12 = 48
In this equation, "t" represents the tortoise's age. The equation states that when Regan was born 12 years ago, the tortoise was already 48 years old.
To solve the equation for "t", we need to isolate the variable on one side of the equation.
Starting with the equation:
t + 12 = 48
We can isolate "t" by subtracting 12 from both sides of the equation:
t + 12 - 12 = 48 - 12
This simplifies to:
t = 36
Therefore, the tortoise is currently 36 years old.
