Question

cassies grandfather has a very old pet tortoise. he told cassie that the tortoise was 48 years old when she was born 12 years ago. cassie is amazed and wants to know how old the tortoise is now. which equation can cassie use to find the tortoises age t? t - 12 = 48 t + 12 = 48 $\frac{t}{12}=48$ 12t = 48 solve this equation for t to find the tortoises age. years

Explanation:

Step1: Analyze the age - relationship

The tortoise was 48 years old 12 years ago. Let the current age of the tortoise be $t$. So, $t-12 = 48$.

Step2: Solve the equation for $t$

Add 12 to both sides of the equation $t - 12=48$. We get $t=48 + 12$.
$t=60$.

Answer:

The equation is $t - 12 = 48$, and the tortoise's age $t = 60$ years.
