Question

find the value of the expression 15 + (81 ÷ z) for z = 3.

Explanation:

Step1: Substitute z with 3

We substitute \( z = 3 \) into the expression \( 15+(81\div z) \), so it becomes \( 15+(81\div 3) \).

Step2: Calculate the division

First, calculate the division part: \( 81\div 3 = 27 \).

Step3: Calculate the addition

Then, add 15 and the result of the division: \( 15 + 27 = 42 \).

Answer:

42
