If (x) is an integer and (3x\ge 24), what is the least possible (x)?

Answer and explanation

Correct answer: (8)

The direct answer is option A, x=8. Since 3x\ge24 and 3 is positive, divide both sides by 3 without changing the inequality sign: x\ge8. The question asks for the least possible integer. The first integer satisfying x\ge8 is 8, so option A is correct. Option B, 7, is too small because 3(7)=21, which is not at least 24. Option C, 9, does satisfy the inequality, since 27\ge24, but it is not the least possible value because 8 is smaller and also works. Option D, 24, also satisfies the inequality, but it is not the least value; it appears to confuse the right side with the answer. The symbol \ge includes the endpoint, so x=8 is allowed. Memory cue: solve the inequality first, then choose the smallest allowed integer.
