Evaluate this expression when h = 5:
{102 – [h x (2 + 7) + 3 x (21 – h)]} ÷ 3
A) 3 (Correct Answer)
B) 9
C) 15
D) 35
Explanation:
Follow these steps to evaluate the expression:
{102 – [h x (2 + 7) + 3 x (21 – h)]} ÷ 3
Replace every h with the value 5. The new expression is {102 – [5 x (2 + 7) + 3 x (21 – 5)]} ÷ 3 = {102 – [5 x 9 + 3 x 16]} ÷ 3 = {102 – [45 + 48]} ÷ 3 = {102 – 93} ÷ 3 = 9 ÷ 3 = 3
