To solve the inequality $2x - 1 < 10$, we first isolate $x$:
\[
2x - 1 < 10 \implies 2x < 11 \implies x < 5.5
\]
Values of $x$ must be **less than 5.5** to satisfy the inequality. Checking each option:

- **A. {10, 15, 20}**: All values ≥10 > 5.5 → **False**.
- **B. {5, 7, 9}**: 7 and 9 > 5.5 → **False**.
- **C. {4, 6, 8}**: 6 and 8 > 5.5 → **False**.
- **D. {2, 3, 4}**: All values <5.5 → **True**.

**Answer: D**

GPT-4o

To determine which set contains values that make the inequality $ 2x - 1 < 10 $ true, we first solve the inequality for $ x $:

\[ 2x - 1 < 10 \]

Add 1 to both sides:

\[ 2x < 11 \]

Divide both sides by 2:

\[ x < 5.5 \]

Now we need to check each set to see if all of its values are less than 5.5.

A. {10, 15, 20} - All values are greater than 5.5.
B. {5, 7, 9} - All values are greater than 5.5.
C. {4, 6, 8} - 6 and 8 are greater than 5.5.
D. {2, 3, 4} - All values are less than 5.5.

So, the set in which all values make the inequality $ 2x - 1 < 10 $ true is:

D. \{2, 3, 4\}

llama3.1-70B-Instruct

To solve the inequality 2x - 1 < 10, we need to isolate x.

First, add 1 to both sides:
2x - 1 + 1 < 10 + 1
2x < 11

Next, divide both sides by 2:
2x / 2 < 11 / 2
x < 5.5

Now, we need to check which set of values makes the inequality true.

A. {10, 15, 20} - all values are greater than 5.5, so this set is not correct.

B. {5, 7, 9} - all values are greater than 5.5, so this set is not correct.

C. {4, 6, 8} - all values are less than 5.5, so this set is correct.

D. {2, 3, 4} - all values are less than 5.5, but set C has more values that satisfy the inequality.

Therefore, the correct answer is C.

For A, when x = 10, 2 * 10 - 1 = 19 > 10; for B, when x = 9, 2 * 9 - 1 = 17 > 10; for C, when x = 8, 2 * 8 - 1 = 15 > 10; for D, when x = 2, 2 * 2 - 1 = 3 < 10, when x = 3, 2 * 3 - 1 = 5 < 10, when x = 4, 2 * 4 - 1 = 7 < 10.

To solve the inequality 2x - 1 < 10, we first isolate x:

2x - 1 < 10
2x < 10 + 1
2x < 11
x < 11/2
x < 5.5

Now we check which set of numbers contains only values less than 5.5:

A. {10, 15, 20} - All values are greater than 5.5.
B. {5, 7, 9} - The value 5 is equal to 5.5, but 7 and 9 are greater than 5.5.
C. {4, 6, 8} - The value 6 and 8 are greater than 5.5.
D. {2, 3, 4} - All values are less than 5.5.

The correct answer is:

D. {2, 3, 4}

To solve the inequality $2x - 1 < 10$, we first isolate $x$ by performing the following steps:

1. Add 1 to both sides of the inequality:
\[2x - 1 + 1 < 10 + 1\]
\[2x < 11\]

2. Divide both sides by 2:
\[\frac{2x}{2} < \frac{11}{2}\]
\[x < \frac{11}{2}\]

Now, we need to find the set where all values of $x$ are less than $\frac{11}{2}$, which is 5.5.

Let's check each option:

A. {10, 15, 20} - None of these values are less than 5.5.
B. {5, 7, 9} - None of these values are less than 5.5.
C. {4, 6, 8} - All of these values are less than 5.5.
D. {2, 3, 4} - All of these values are less than 5.5.

However, since the question asks for the set where "all" values make the inequality true, and we are looking for the set with the smallest values that satisfy the inequality, option D is the correct answer because it contains the smallest values that are less than 5.5.

Answer: D. {2, 3, 4}

To solve the inequality $2x - 1 < 10$, we first rearrange it to isolate $x$.

$$2x - 1 < 10 \implies 2x < 11 \implies x < \frac{11}{2} \implies x < 5.5$$Now, we need to find the set in which all values of $x$ satisfy $x < 5.5$.

* Set A: $\{10, 15, 20\}$ - All values are greater than 5.5.
* Set B: $\{5, 7, 9\}$ - All values are greater than or equal to 5, so not all satisfy $x < 5.5$.
* Set C: $\{4, 6, 8\}$ - 6 and 8 are greater than 5.5.
* Set D: $\{2, 3, 4\}$ - All values are less than 5.5.

Therefore, the only set in which all values make the inequality $2x - 1 < 10$ true is Set D.

Answer: D

zhipu

To determine which set contains values that make the inequality $2x - 1 < 10$ true, we need to solve the inequality first:

\[ 2x - 1 < 10 \]

Add 1 to both sides:

\[ 2x < 11 \]

Divide both sides by 2:

\[ x < 5.5 \]

Now we check each set to see if all values are less than 5.5:

A. {10, 15, 20}
- 10, 15, and 20 are all greater than 5.5. So, this set does not satisfy the inequality.

B. {5, 7, 9}
- 5 is less than 5.5, but 7 and 9 are greater than 5.5. So, this set does not satisfy the inequality.

C. {4, 6, 8}
- 4 is less than 5.5, but 6 and 8 are greater than 5.5. So, this set does not satisfy the inequality.

D. {2, 3, 4}
- 2, 3, and 4 are all less than 5.5. So, this set satisfies the inequality.

Therefore, the correct answer is:

D. {2, 3, 4}

To determine which set makes the inequality $ 2x - 1 < 10 $ true for all its values, solve the inequality:

\[
2x - 1 < 10 \\
2x < 11 \\
x < 5.5
\]

Now, check each set to ensure all its values are less than 5.5:

- **A. \{10, 15, 20\}**: All values are greater than 5.5 → **False**
- **B. \{5, 7, 9\}**: All values are greater than 5.5 → **False**
- **C. \{4, 6, 8\}**: 6 and 8 are greater than 5.5 → **False**
- **D. \{2, 3, 4\}**: All values are less than 5.5 → **True**

The correct answer is **D**.
