Answer:

Choice B and Choise C.

Step-by-step explanation:

Equivalent expressions are those expressions that have the same value but they look different.

Given the following expression provided in the exercise:

[tex]6.53 - (-4.11) + 7.92[/tex]

You need to remember the multiplication of signs in order to find the equivalent expressions:

[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]

Then:

- Eliminating the parentheses, you get this equivalent expression:

[tex]6.53 +4.11 + 7.92[/tex]

- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:

[tex]-(-6.53)+4.11-(-7.92)[/tex]

This is an equivalent expression to [tex]6.53 - (-4.11) + 7.92[/tex]
