An equation can be broken down into expressions, terms, variables, constants, and coefficients. In the equation 0.4−7x=3 , what is/are the constant(s) in the equation?

In the equation \( 0.4 - 7x = 3 \), the constants are the numbers that do not change, which are not multiplied by a variable. In this case, the constants are:

- \( 0.4 \)
- \( 3 \)

Therefore, the correct response is:

**0.4 and 3**
