Perform the indicated operation. 11-6 /7-7
what the answer my answer is 5/7 is that right.
Add-26+(-29). I said 55 is the answer is that right. I am confused.
11-6 /7-7 = 5/0 = 5
-26+(-29) = -55
Division by zero undefined!
Thanks Damon. I figured that 5 divided by nothing was still 5.
Nope. I had typed replies to this but was kicked off line, then when I came back I saw your reply.
try dividing 5 by .0000001 on calculator :)
Good heavens!!
I see why it's undefined! Thanks.
I also rethought my original idea -- and see the logic of undefined. :-)
To solve the expression 11 - 6 / 7 - 7, you need to follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
1. Perform the division first: 6 / 7 = 0.857142857 (approximately).
Now, we have the expression: 11 - 0.857142857 - 7.
2. Perform the subtraction: 11 - 0.857142857 = 10.142857143 (approximately).
Now, we have the expression: 10.142857143 - 7.
3. Perform the final subtraction: 10.142857143 - 7 = 3.142857143.
So, the correct answer is approximately 3.142857143. Rounded to three decimal places, it can be written as 3.143 or as a fraction, 3143/1000.
Regarding the expression: -26 + (-29), when you add two negative numbers, the result will be negative.
-26 + (-29) = -55
Therefore, your initial answer of 55 is incorrect. The correct answer is -55.
