Answer 1

To identify which of the provided responses are equations, we need to look for statements that equate something like two expressions with an equals sign. Here are the choices you have provided:

1. \( -2x = 14 \) (This is an equation)
2. \( x4.5 = 10.2 \) (This is not properly formatted. If it means \( x \times 4.5 = 10.2 \), then it is an equation; otherwise, it does not make sense as written.)
3. \( z7 + 1 = z \) (This is not an equation based on standard notation. It appears to be an incorrect format.)
4. \( 25 - q = 25 - q \) (This is an equation, as it equates both sides.)
5. \( p + 6 = 10 \) (This is an equation.)

From the above, the valid equations would be:

1. \( -2x = 14 \)
2. \( x4.5 = 10.2 \) (assuming it’s meant to imply multiplication)
3. \( 25 - q = 25 - q \)
4. \( p + 6 = 10 \)

So the correct answers are:

1. \( -2x = 14 \)
2. \( x4.5 = 10.2 \) (or if this is interpreted as an equation)
3. \( 25 - q = 25 - q \)
4. \( p + 6 = 10 \)

You should check the answers using the provided feature to confirm which are recognized as equations properly. But based on standard understanding, these would be correct selections if interpreted as equations.
