help please just the answers i will medal and fan
help @pyxieyt
the questions r in the attachment
All?
yes please
16. B 17. C 18. D 19. B
Can anyone check if got the ones above correct? I would not want to give the wrong answers.
its ok
20.A 21.C 22.D Hope i got it right
20. D 21. D 22. A That should be all. :D I tried my best, so I apologize in advance if there are wrong answers. If you want to stick around for another opinion, that would be best.
Oh to different answers XD
20. has to be less than 6
Well, for 20, dividing by a negative changes the direction of the inequality sign. That is why it is D and not A.
that (-1) i thought it was minus one xD
20 is: -0.3n is less than or equal to 5.4 Are we talking about the same problem? Not sure where you get 6 and -1....that should be 22
I was talking about 22. Sorry XD
So it is 20. D 21. ? 22. D Right?
That's fine, buddy. :D Well, for 22, you would add 1 to both sides... x<7 The only one with an open circle, meaning that it is NOT equal to anything, is A.
You helped me out XD thanks
You're welcome. :) Now, for 21, you can immediately rule out C because the inequality has to be MORE THAN 380, as stated in the problem. They collected more than 380 cans, NOT at least 380 cans. You can rule out A because the inequality is less than 380 cans, which isn't what we are looking for. You know that 145 cans PLUS ''c'' will be more than 380 cans: 145+c > 380 Subtracting 145 from both sides gets you: c >235 The answer, therefore, has to be D. If you have any more questions on how I got the answers, please let me know. You might still want to get another opinion, just in case I am wrong. I hope I have helped! :D
Please understand, all of you, that asking "just for answers" and providing answers with no explanation or work is FORBIDDEN on OpenStudy.
Don't you want to develop the skills necessary to solve these problems on quizzes or tests? If so, learn and practice solving these problems.
Yes, I am sorry. I have explained several of my answers, but not all of them. I will explain the rest of them, then. I hope you can forgive me, mathmale.
I am very sorry. I will try to explain my answers too. @mathmale
I realised on most I made mistakes.
For, 16, you see that the line goes toward the left. The numbers included are SMALLER than -2, so the answer must hold that to be true. There is also a black circle at -2, meaning it is included in the inequality (equal to). You can eliminate A and C, since neither of the inequalities have ''equal to'' symbols. You can eliminate D, which says that x is BIGGER than -2, which is NOT TRUE. The only answer choice left is B.
For 17, notice that it says ''at least 6''. This can be translated as ''....or equal to 6''. The answer must contain the ''equal to'' symbol. A and B are eliminated, then. Since AT LEAST 6 people applied for the job, this means there can be more (least is minimum). D is therefore eliminated. The only inequality satisfying all of these criteria is C.
For 18, you must solve for x by ''isolating'' it. Subtract 17 from both sides. You get: x is less than or equal to -22. The only inequality that matches this is D.
For 19, you must solve for z. To do this, you must divide by 4. This gets you: z > -15 The answer, therefore, is B.
@mathmale, I have finished explaining all my problems. I hope they are satisfying to you. If you have any questions, please let me know. In an earlier message, I sincerely apologized for not having all of my explanations complete. From now on, I shall explain faster and completely. :D
