From left to right, evaluate the expression:
−6 + 9/−3
To divide two numbers, we need to take the reciprocal of the second number and multiply:
−6 + 9 × (−1/3)
Multiply the numbers:
−6 + (−9/3)
Simplify:
−6 + (−3)
Combine like terms:
−9
Answer: B) −9
To evaluate −6+9/−3, we follow the order of operations (also known as PEMDAS or BODMAS).
Step 1: Evaluate the division 9/−3 first.
9 divided by −3 is equal to −3.
Step 2: Substitute the result of the division back into the original expression.
−6 + (−3)
Step 3: Evaluate the addition.
−6 + (−3) is equal to −9.
Therefore, the correct answer is:
A. −1
To evaluate the expression −6+9/−3, we need to follow the order of operations, which is commonly referred to as PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction).
First, we calculate the division part of the expression, which is 9/−3. Dividing 9 by −3 gives us −3:
−6 + (9/−3)
−6 + (−3)
Next, we perform the addition:
−6 + (−3)
= −9
Therefore, the answer is −9.
None of the provided answer choices match our calculated result of −9.
