BEST ANSWER GETS BRAINLIEST!! PLEASE HELPP
Samantha's age is 3 years more than half her uncle's age. If her uncle's age is z years, which of the following expressions best shows Samantha's age?

Fraction z over 3 + 2
Fraction z over 2 + 3
z + 3
3z

Answer 1

The expression for the situation will be 3+1/2z Or z/2+3

Answer 2

Answer:

Hence, the expression for Samantha's age is given by:

Fraction z over 2 + 3

Step-by-step explanation:

It is given that:

Samantha's age is 3 years more than half her uncle's age.

Her uncle's age is given to be z years.

So, Samantha's age can be expressed mathematically in the form of algebraic expression as:

$\dfrac{z}{2}+3$

( Since half the uncle's age means z/2 and 3 more than that quantity is:

z/2+3)

Hence, the correct option is: i.e. the expression for Samantha's age is given as:

Fraction z over 2 + 3
