Answer 2

b. z divided by 2 + 3

Explanation:

Samantha's age is 3 years more than half her uncles age. If her uncles age is z years which of the expression best shows Samantha's age.

Let

uncle age = z

Recall her age is 3 years more than half her uncles age

half her uncles age = z/2

Her age will be adding 3 years to 1z/2

Samantha's age = 3 + z/2

Samantha's age = 3 + z/2

Samantha's age = z/2 + 3

Samantha's age = z divided by 2 + 3
