Multiple Choice Question
Evaluate.
-6+9/-3
A. -1
B. -5
C. 3
D. 5
The answer is A. -1
To evaluate the expression -6 + 9 / -3, we need to follow the order of operations (PEMDAS/BODMAS).
Step 1: Divide 9 by -3
9 / -3 = -3
Step 2: Add -6 to the result
-6 + (-3) = -6 - 3 = -9
So the answer is -9, which is not one of the options given. Therefore, none of the available options is correct.
To evaluate the expression -6 + 9 / -3, we need to use the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). According to this rule, we perform any calculations inside parentheses first, then evaluate any exponents, followed by multiplication and division from left to right, and finally perform addition and subtraction from left to right.
In this expression, there are no parentheses or exponents, so we can proceed with multiplication and division.
First, we need to divide 9 by -3. Dividing 9 by -3 gives us -3.
Then we add -6 to -3, which gives us -6 + (-3) = -9.
Therefore, the answer to the expression -6 + 9 / -3 is -9.
None of the answer choices given matches the correct answer of -9.
