2) -0.4
3) 0.4p
4) 0.4

Answer 1

The equivalent expression to -0.91p + 0.51p is -0.40p, which is obtained by adding the coefficients of p. This is option 1 among the provided choices.

Step-by-step explanation:

The question asks for the equivalent expression to the problem -0.91p + 0.51p. To find the equivalent, we combine like terms.

First, we add together the coefficients of the variable p:

-0.91 + 0.51 = -0.40

Now we reattach the variable p to the combined coefficient to get the simplified expression:

-0.40p

Therefore, the equivalent expression is -0.40p, which corresponds to option 1 in the multiple-choice answers provided.
