Answer

The solutions to the inequalities are: 1. \( x \leq 15 \) 2. \( x > 14 \) 3. \( x \leq 3 \) 4. \( x \geq 28 \) 5. \( x < 13 \)

Solution

To solve the given inequalities, we will translate each statement into an inequality and then solve for \( x \). 1. The quotient of \( x \) and 3 is less than or equal to 5: \[ \frac{x}{3} \leq 5 \] 2. The difference between \( x \) and 4 is greater than 10: \[ x - 4 > 10 \] 3. The product of \( x \) and 7 is not greater than 21: \[ 7x \leq 21 \] 4. \( x \) decreased by 13 is at least 15: \[ x - 13 \geq 15 \] 5. \( x \) minus 5 is less than 8: \[ x - 5 < 8 \] Now, let's solve each inequality step by step. Solve the inequality by following steps: - step0: Solve for \(x\): \(\frac{x}{3}\leq 5\) - step1: Multiply both sides: \(\frac{x}{3}\times 3\leq 5\times 3\) - step2: Multiply the terms: \(x\leq 15\) It seems there was an error in solving the equation \( x - 4 > 10 \). Let's solve it manually. The equation \( x - 4 > 10 \) can be solved by adding 4 to both sides: \[ x > 14 \] Now, let's solve the next inequality. Solve the inequality by following steps: - step0: Solve for \(x\): \(7x\leq 21\) - step1: Divide both sides: \(\frac{7x}{7}\leq \frac{21}{7}\) - step2: Divide the numbers: \(x\leq 3\) Solve the equation \( x - 13 \\geq 15 \). Solve the inequality by following steps: - step0: Solve for \(x\): \(x-13\geq 15\) - step1: Move the constant to the right side: \(x\geq 15+13\) - step2: Add the numbers: \(x\geq 28\) Solve the equation \( x - 5 < 8 \). Solve the inequality by following steps: - step0: Solve for \(x\): \(x-5<8\) - step1: Move the constant to the right side: \(x<8+5\) - step2: Add the numbers: \(x<13\) The solutions to the given inequalities are: 1. \( x \leq 15 \) 2. \( x > 14 \) 3. \( x \leq 3 \) 4. \( x \geq 28 \) 5. \( x < 13 \)

Bonus Knowledge

When it comes to inequalities, they can serve as powerful tools in real-life scenarios! For example, if you’re planning a budget, you can express how much you can spend on various items by writing inequalities that reflect your financial limits. This way, not only can you keep your expenses under control, but you can also make smarter choices based on these calculations—who knew math could be so practical? One common mistake people make with inequalities is forgetting to flip the inequality sign when multiplying or dividing by a negative number. For instance, if you have \(-2x \leq 6\), dividing both sides by \(-2\) gives you \(x \geq -3\). It’s a tiny slip that can lead to incorrect conclusions, so always double-check those signs!
