If Anne’s age is represented by the variable a then express Jenny’s age in terms of a if Jenny is three years less than half of Anne’s age

J = a/2 - 3

To express Jenny's age in terms of Anne's age, we can start by breaking down the given information.

We are told that Jenny's age is three years less than half of Anne's age. Let's use this information to write an expression for Jenny's age.

First, we represent Anne's age with the variable "a."

Half of Anne's age can be represented as (1/2)a.

Jenny's age is three years less than half of Anne's age, which can be expressed as (1/2)a - 3.

Therefore, the expression for Jenny's age in terms of Anne's age "a" is (1/2)a - 3.
