Question:I am so desperate for an A, I have had the 90% streak for 11 tests in a row and 3 88%. Now my grade is 92.4%. Here's what I do to study for a test
1 I have a tudor that helps 2 hours the day before the test
2 I study 5 hours plus
3 While taking my test I double check, if not triple check
4 I know every concept by heart
5 I take 2 pretests
6 I take my time and continue to check until the bell
7 all of my homework is 98% accurate (human error)
I have no idea why I do so poorly on these tests, all of it is right, I just get 2 for calculator errors and 2 for switching the negative signs, so it's pretty pathetic. Then my score is like 32/36, so I end up with a B+. I really need an A this semester, and I have 2 more tests. Any suggestions would be so appreciated. Please!
Or am I just a naturally awful math test taker, I'm very logical, and think things through, I suppose that that doesn't count in the real world.
Answers:Answer the questions you know well first; leave the questions that are tough to the end, allowing you to positively utilize the amount of test time given. Study with friends, have them check over your work before you do, as people generally are unlikely to notice their own errors as opposed to errors made by others. Work on study guides given out by your teacher covering the test material. If your teacher doesn't hand out study guides, then practice study guides from other teachers at your school covering the same material, or even online study guides. Otherwise, expose yourself to material three times: the original covering by the material, writing it down by hand, and studying your notes. Good luck on your test.

Question:Question 1 (Multiple Choice Worth 4 points)
[6.01] Systems of equations with different slopes and different yintercepts have more than one solution.
Always
Sometimes
Never

Question 2 (Multiple Choice Worth 4 points)
[6.03] What is the value of the x variable in the solution to the following system of equations?
3x + 2y = 8
2x + 3y = 2
4
2
x can be any number as there are infinitely many solutions to this system
There is no x value as there is no solution to this system

Question 3 (Multiple Choice Worth 4 points)
[6.02] and [6.03] What is the value of the x variable in the solution to the following system of equations?
4x + y = 8
x 2y = 2
0
2
There is no x value as there is no solution to this system
x can be any value as there are infinitely many solutions to this system

Question 4 (Multiple Choice Worth 4 points)
[6.03] If you wanted to eliminate the y variable in the following system, what could be your first step?
x y = 6
4x 3y = 12
Add the two equations together
Multiply the first equation by 4
Multiply the first equation by 3
Multiply the first equation by 3

Question 5 (Multiple Choice Worth 4 points)
[6.02] Use a system of equations to solve the following problem: Fairview High School has a total of 92 boys and girls who play sports. If the number of boys is 17 more than twice the number of girls, how many boys play sports at this high school?
25
75
67
84

Question 6 (Multiple Choice Worth 4 points)
[6.02] Breann solved the system of equations below. What mistake did she make in her work?
2x + y = 5
x 2y = 10
y = 5 2x
x 2(5 2x) = 10
x 10 + 4x = 10
5x 10 = 10
5x = 20
x = 4
2(4) + y = 5
y = 3
She should have substituted 5 + 2x
She combined like terms incorrectly, it should have been 4x instead of 5x
She subtracted 10 from both sides instead of adding 10 to both sides
She made no mistake

Question 7 (Multiple Choice Worth 4 points)
[6.03] The three Math Idol judges have been eliminating contestants all day! The number of onestep equations and twostep equations who have been eliminated today is equal to 840! If three times the number of onestep equations minus twice the number of twostep equations is equal to 870, how many onestep equations auditioned today?
330
510
520
660

Question 8 (Multiple Choice Worth 3 points)
[6.02] For the following system, if you isolated y in the first equation to use the Substitution Method, what expression would you substitute into the second equation?
4x y = 8
2x + 3y = 9
8 4x
8 + 4x
8 + 4x
8 4x

Question 9 (Multiple Choice Worth 4 points)
[6.01] Systems of equations with different slopes and different yintercepts have no solutions.
Always
Sometimes
Never

Question 10 (Multiple Choice Worth 5 points)
[6.01] Select the system of equations that corresponds to the given graph.
4x + y = 6
6x + 3y = 6
3x + y = 2
4x + 2y = 4
2x + y = 4
6x + 3y = 12
4x + 2y = 6
6x + 3y = 12

Question:I have a math problem, and i keep getting odd answers.
1.05x15.41<2.55x47.09
I would like explinations for the steps. you dont need to provide an answer, i have one, i just dont know how to get to it. Please no comments of "how can you be so stupid as to not get that problem" cuz i feel stupid enough already.
answer= (8,infinity) or x>8, okay, now i find out its also x<8.8 any explinations?

Question:Plz help me answer this question and please show how you got the answer. I got this question wrong on a test and i want to figure out what i did wrong.
A recent survey of Americans who work outside the home found that 10% take public transportation,80% drive 2 work & 10% use other forms of transportation. Megan used a random # generator to simulate the various methods that a group of five people may use to get 2 work. For her simulation, she assigned digits to various methods of transportation shown below.
RANDOM DIGIT:TYPE OF TRANS.
0 : public
18: drive
9 : other
> she ran her simulation 10 time & her results are below
69969; 80939; 49510; 73686; 62625; 19598; 31305; 40702, 62385, 67996.
Based on Megan's simulation, what is the probability that all 5 people in the group drive 2 work.
This is the whole problem. plz answer it and show how you got ur answer. i rly need help with this. THANK YOU! don't forget u could get 10 points
Answers:699692 people drove, 3 other 809392 people drove, 1 public, 2 other 495103 people drove, 1 public, 2 other 736865 people drove 626255 people drove 195983 people drove, 2 other 313054 people drove, 1 public 407023 people drove, 2 public 623855 people drove 679963 people drove, 2 other Okay, so you have 2 possible outcomes, at least two that matter: All five people drove, or not all five people drove. There are 10 results from Megan's simulation. In 3 out of the 10, all five people drove. In the other 7, not all five people drove. Based on her simulation, the probability that all 5 people in the group drive to work is 3/10. Hope I've helped!
