Jacob finds Hannah's age to be 16 years. Is he correct explain.

Answer 1

Hannah is 7years old and Kayla is 23 years old.

Step-by-step explanation:

Kayla's age = 2 × Hanna's age + 9

Kayla - Hannah = 16

or, 2H +9 - H = 16

or, H = 16- 9

or, Hannah = 7 years

Therefore,

Kayla = 2H + 9

= 2×7 +9

= 23 years.
