The correct Answer is:
To solve the inequality \(-3 < \frac{4}{3}h + \frac{1}{6} < 1\) and find a possible value of \(12h - 4\), we will follow these steps: ### Step 1: Multiply the entire inequality by 9 Since we want to eliminate the fractions, we can multiply the entire inequality by 9 (a positive integer, which does not change the inequality signs). \[ -3 \times 9 < \left(\frac{4}{3}h + \frac{1}{6}\right) \times 9 < 1 \times 9 \] This simplifies to: \[ -27 < 12h + \frac{3}{2} < 9 \] ### Step 2: Subtract \(\frac{3}{2}\) from all parts of the inequality Next, we need to isolate \(12h\). We can do this by subtracting \(\frac{3}{2}\) from each part of the inequality. \[ -27 - \frac{3}{2} < 12h < 9 - \frac{3}{2} \] Calculating the left side: \[ -27 = -\frac{54}{2} \quad \text{so} \quad -\frac{54}{2} - \frac{3}{2} = -\frac{57}{2} \] Calculating the right side: \[ 9 = \frac{18}{2} \quad \text{so} \quad \frac{18}{2} - \frac{3}{2} = \frac{15}{2} \] Thus, we have: \[ -\frac{57}{2} < 12h < \frac{15}{2} \] ### Step 3: Write the inequality for \(12h - 4\) Now, we want to find the range of \(12h - 4\). We can express this as: \[ 12h - 4 = 12h + (-4) \] To find the new bounds, we subtract 4 from each part of the inequality: \[ -\frac{57}{2} - 4 < 12h - 4 < \frac{15}{2} - 4 \] Calculating the left side: \[ -4 = -\frac{8}{2} \quad \text{so} \quad -\frac{57}{2} - \frac{8}{2} = -\frac{65}{2} \] Calculating the right side: \[ -4 = -\frac{8}{2} \quad \text{so} \quad \frac{15}{2} - \frac{8}{2} = \frac{7}{2} \] Thus, we have: \[ -\frac{65}{2} < 12h - 4 < \frac{7}{2} \] ### Step 4: Choose a possible value From the inequality \(-\frac{65}{2} < 12h - 4 < \frac{7}{2}\), we can choose any value in this range. For instance, we can choose \(2\) as a possible value since: \[ -\frac{65}{2} \approx -32.5 \quad \text{and} \quad \frac{7}{2} = 3.5 \] Thus, \(2\) is a valid choice. ### Final Answer One possible value of \(12h - 4\) is \(2\).

To solve the inequality \(-3 < \frac{4}{3}h + \frac{1}{6} < 1\) and find a possible value of \(12h - 4\), we will follow these steps: ### Step 1: Multiply the entire inequality by 9 Since we want to eliminate the fractions, we can multiply the entire inequality by 9 (a positive integer, which does not change the inequality signs). \[ -3 \times 9 < \left(\frac{4}{3}h + \frac{1}{6}\right) \times 9 < 1 \times 9 \] ...
