Point A is at -20. Point B is 5 less than point A, which means subtracting 5 from -20:
\[
\text{Position of B} = -20 - 5 = -25
\]
On a number line, smaller numbers (more negative) are to the left. Since -25 is smaller than -20, point B is to the **left** of point A.

Analyzing the options:
- **A** incorrectly states B is to the right.
- **B** and **D** have the wrong position (-15).
- **C** correctly states B is at -25 and left of A.

baichuan4 Point B is located at -25 (since it is 5 less than point A, which is at -20). Since it is more negative than point A, it is to the left of point A on the numberline.

Answer: C		 C
doubao C. Point A is at -20 and point B is 5 less than point A, so point B is at -20 - 5 = -25. -25 is to the left of -20 on the numberline. C

zhipu To determine the location of point B, we start with the information that point A is at -20 and point B is 5 less than point A.

\[ \text{Point B} = \text{Point A} - 5 = -20 - 5 = -25 \]

Now we need to decide which statement about point B is true:
- Point B is located at -25.
- On a number line, numbers decrease as you move to the left and increase as you move to the right.

Since -25 is less than -20, point B is to the left of point A.

Let's review the options:
A. It is located at -25 and is to the right of point A on the numberline. (Incorrect, -25 is to the left of -20)
B. It is located at -15 and is to the right of point A on the numberline. (Incorrect, point B is at -25, not -15)
C. It is located at -25 and is to the left of point A on the numberline. (Correct)
D. It is located at -15 and is to the left of point A on the numberline. (Incorrect, point B is at -25, not -15)

Therefore, the correct answer is:

deepseekv3 To solve this question, let's follow these steps:

1. **Find the location of point B**:
Point A is at -20, and point B is 5 less than point A.
So, point B is located at:
\(-20 - 5 = -25\).

2. **Determine the position of point B relative to point A on the numberline**:
On a numberline, numbers decrease as you move to the left. Since -25 is less than -20, point B is to the **left** of point A.

3. **Match the correct statement**:
The correct statement is:
**"It is located at -25 and is to the left of point A on the numberline."**

Thus, the correct answer is:

**C**		 C
