Question

Samya's dog is ⅓ as old as her. In 5 years, her dog will be ½ as old as her. Write an equation to represent this situation. How old is Samya's dog?

a. d = (1/3)a
b. d + 5 = (1/2)(a + 5)
c. a = 3d
d. a + 5 = 2(d + 5)

Answer 1

The equation that represents this situation is d + 5 = (1/2)(a + 5). To find out how old Samya's dog is, we need more information or another equation that relates both their ages.

Step-by-step explanation:

The equation that represents this situation is d + 5 = (1/2)(a + 5). Let's break it down step-by-step:

1. Samya's dog is ⅓ as old as her. We can represent Samya's age as a and her dog's age as d.
2. In 5 years, her dog will be ½ as old as her. So, we need to add 5 to both Samya's and her dog's age and set up an equation: a + 5 = 2(d + 5).
3. Simplifying the equation gives us the final equation: d + 5 = (1/2)(a + 5).
