Given:
Given the inequalities:4

Required: Identify the inequality in which x = 8 is a solution.
Explanation:
Substitute 8 for x in each inequality and check whether it satisfies the inequality.
Consider 4x + 3 > 0.

So, x = 8 satisfies the inequality 4x + 3 > 0.
Consider 9x - 5 < 100.

So, x = 8 satisfies the inequality 9x - 5 < 100.
Consider x + 4 ≤ 10.

So, x = 8 not satisfies the inequality.
Consider 72 ÷ x ≥ 4.

So, x = 8 satisfies the inequality.
Final Answer: The inequality in which x = 8 is not a solution is x + 4 ≤ 10.
Answer: C
Explanation: We need to combine like terms, which means 7a and -12a and -8 and 4
7-12=5 and -8+4=-4
3.0, because the 3 is in the ones place.
