Answer 1

To determine which of the provided statements are equations, we must recognize that an equation is a mathematical statement that asserts the equality of two expressions, typically containing an equals sign (=).

Here are the provided options analyzed:

1. **25 - q**: This is not an equation; it is just an expression.

2. **x4.5 = 10.2**: This is an equation because it contains an equals sign.

3. **2/3m**: This is not an equation; it is just an expression.

4. **−2x = 14**: This is an equation because it contains an equals sign.

5. **9 = 13 − b**: This is an equation because it contains an equals sign.

6. **z/7 + 1**: This is not an equation; it is just an expression.

7. **p + 6 = 10**: This is an equation because it contains an equals sign.

8. **k + 5.8**: This is not an equation; it is just an expression.

Based on this analysis, the equations from the list are:

- x4.5 = 10.2
- −2x = 14
- 9 = 13 − b
- p + 6 = 10

You should select:

- x4.5 = 10.2
- −2x = 14
- 9 = 13 − b
- p + 6 = 10
