Can You Find the Mistake?

Hello Students!

For this week's online blog assignment, please respond to the following prompt:






With your knowledge of solving equations, analyze Derek's work with this equation. Is his answer reasonable? Where did he go wrong (Step 1 or Step 2)? What can Derek do to ensure he gets the correct solution?

In your response, answer each of the questions in bold above. Be sure you answer ALL of the questions COMPLETELY. Your response could be in the form of sentences or bullet points.

Reminders:
  • Your response to this blog post AND another student in the class' post is due on SUNDAY, 03/19/2017 at 10pm ChST.
  • Be sure to respond to the prompt FIRST, then respond to the post of another student in the class.
  • Use any vocabulary terms that you've learned that could be relevant in your response.



Have fun blogging! I can't wait to read your responses!

  2. i agree to that because you also have to find the stated equation by finding it step by step you also have to solve the problem equally.

  3. i agree with the operation because to find the answer that its telling us to find, we have to do what its telling us to do. we have to do it step by step and make sure the answer is correct.

  4. I do not agree to Derek's answer on the problem because the his answer is eight when the correct answer is nine. He was doing fine in step one, but once it came to step two he made a mistake. It is right that he needed to divide because that is the inverse operation of multiplication, so he needed to divide 8 to both sides. When he divided 8 to 72 he said the answer was eight, but it is nine (he divided wrong). A way to check your work next time is to rewrite the equation, substitute the variable with the answer you got, then if it is equal then you're correct.

    1. i agree with your answer; that it should be 9 instead of 8.

  5. I disagree with Derek's answer in step 2 because his answer should be 9. He was okay in step 1, but in step 2, he divided the numbers wrong. 8 divided by 72 is 9, so the answer should be 9, instead of 8.

  6. @John Paul I don't get what you're trying to say! Next time explain better. Though i agree to what you stated saying about solving the problem equally.

  7. I disagree on Derek's answer on the problem because the answer would be nine not eight. He was correct on step 1, but when he came to step two he had a mistake. He was correct with step one but when you divide 72 by eight the answer would be something else. The answer would be nine. When you are going to check your work you substitute the answer you got to the equation and check if it is right.

  9. i disagree with dereks answer in the 2 step equation his own answer should be 9 he was okay with the 1 step equation but the 2 step he divided the number wrong

  10. @ RAMONA i disagree with the thing the answer should be 9 not 8

  11. I disagree with Derek's problem because the answer should be 9 not 8 so his mistake is only the answer.

  12. @ Nate I agree with your answer and I like how you explained good.

  13. I disagree with Derek's answer . The reason why I disagree is because, he divided 72 to 8 and he got 8 , which is not suppose to be 8 , it is suppose to be 9, Because 8x8 does not equal to 72 it equals to 64 , but 8x9 equals to 72 , so the answer to Derek's problem should be 9.

    1. I agree with Cindy because 8*9=72. Cindy you did a good job on explaining why you disagree with Derek's problem.

    1. i agree with you @cindy because yes Derek must of thought the opposite.

  15. i agree with cindy because yes 8x9=72 good job cindy.

  16. Derek's answer is incorrect, in which I would agree on. This is due to his quotient being wrong. The correct solution to that was 9. However, he had his solution to the problem as d=8. If it were to be written down (8d=72), that will be incorrect. As you can see, 8 * 8 will give you the product of 64 instead of 72. Again, Derek's quotient, solution, answer, or whatsoever is incorrect.

  17. I disagree with Derek's answer. I disagree because 72 divided by 8 is 9. Also 8(8) does not equal to 72 it equals to 64. In the other hand 9(9) equals to 72. So Derek's answer is wrong.

  18. I disagree with Derek's answer because when you divide 72 to 8 it will equal to 9, 9*8=72 so that is how you will get your answer. Derek did the other steps correct but when it cam to the division part he got it wrong. So Derek just got the value of the variable wrong.

    1. I agree with you because 72 divided by 8 is 9.

    2. I agree with you, Tori. If he checked his work by multiplying, he would've gotten it.

  19. @Jovilyn I concur on yond with thee. Good explanation on how to check your work. And one way to do that is by substituting the variable or doing the inverse operation to check it. Sometimes, we would solve our work so fast without even checking if they are the right solutions. Unfortunately for Derek, his quotient to that one step equation problem was incorrect.

  20. I disagree with Derek's answer because 8 divided by 72 is nine so his answer i wrong.

  21. yes i think derekmade a mistake in mutltipplying because usually people would think that 8 times eight would be a higher number which is why he made the mistake in the first place whichis why we would need to check our work

  22. Derek made a mistake. He divided it wrong. He made the mistake in step 2. instead of dividing i think he kept the 8 on the left and crossed out the right side.Derek should of checked his work by doing the check.

  23. i disagree with Derek's answer because when you divide 72 to 8 it does not equal to 8. It equals to 9. so his answer was supposed to be 9.

  24. I disagree with Derek's answer because he did the equation wrong or the problem wrong because the correct is answer is 9 not 8.

  25. I disagree with Derek's answer because in step two, he divided 72 by 8 wrong. 72 % 8 would equal 9, and to ensure that the answer is 9, we multiply 8 by 9. Which would equal to 72.
