which number line represents the solution to the inequality 1.6w - 1 > 5.4?
which number line represents the solution to the inequality 1.6w - 1 > 5.4?
Answer
Explanation:
Step1: Solve the inequality
$$ \begin{align*} 1.6w - 1 &> 5.4\ 1.6w&>5.4 + 1\ 1.6w&>6.4\ w&>\frac{6.4}{1.6}\ w&>4 \end{align*} $$
Step2: Analyze the number - line representation
The solution (w > 4) means that on the number line, there is an open circle at (4) (because (4) is not included in the solution set) and the line extends to the right (towards larger numbers).

B.
