Question
Which of the numbers 6, 7, and 8 is a solution of 3x≤18
?(1 point)

Answer 1

To determine which of the numbers 6, 7, and 8 is a solution to the inequality \(3x \leq 18\), we can substitute each number into the inequality:

1. For \(x = 6\):
\[
3(6) = 18 \quad \Rightarrow \quad 18 \leq 18 \quad \text{(True)}
\]

2. For \(x = 7\):
\[
3(7) = 21 \quad \Rightarrow \quad 21 \leq 18 \quad \text{(False)}
\]

3. For \(x = 8\):
\[
3(8) = 24 \quad \Rightarrow \quad 24 \leq 18 \quad \text{(False)}
\]

The only number that satisfies the inequality \(3x \leq 18\) is \(6\). Therefore, the solution is:

**6**
