ANSWER
C. 7
EXPLANATION
We want to evaluate
[tex]2 - ( - 8) + ( - 3) [/tex]
We use the order of operations PEDMAS.
Dealing with the parenthesis first,we have
[tex]2 - - 8+- 3[/tex]
Note that:
[tex] - - = + [/tex]
and
[tex] - + = - [/tex]
Our expression now becomes:
[tex]2 + 8 - 3[/tex]
Next, we add to get:
[tex]10 - 3[/tex]
We finally subtract to get,
[tex]7[/tex]
The correct answer is C
Hello!
The answer is: C. 7
Why?
To solve the problem, first, we need to consider the signs out and inside of the parenthesis.
We must remember the following rule:
[tex]--=+\\+-=-[/tex]
We are given the following expression:
[tex]2-(-8)+(-3)[/tex]
Then, we can rewrite it using the rule of the signs, we have:
[tex]2--8+-3=2+8-3=2+8-3[/tex]
[tex]2+8-3=10-3=7[/tex]
Hence, the correct option is C. 7.
Have a nice day!
