Math NET help?

You want to get ALL the Ms on one side and all the numbers on one side simply stated

5m + 8 = 3(m+4)

Distribute 3 to m and 4

5m+8=3m+12

subtract 3m from the right

2m+8=12

subtract 8 from the right

2m=4

divide by 2

m=2

Plug the 2 back in to the M and check to see if correct

5(2) + 8 = 3(2+4)

10+8=6+12

18=18

6(t+3) + 8 - 5(t+2) =0

distribute 6 to t and 3

6t+18+8-5(t+2)

distribute 5 to t and 2

6t+18+8-5t-10=0

add the ts and numbers together

t+26-10=0

subtract the t

26-10=-t

16=-t

multiply by (-1) to get a positive t

-16=t

Plug -16 into t to check if correct

6(-16+3) + 8 - 5(-16+2)=0

-96+18+8-(-80+10)=0

-70-(-80+10)=0

REMEMBER -*-= POSITIVE so

-70+80-10 = 0

Ok.....a little confusing at first but I get the steps I need to take and how you got the answer. Thank you so much!!!!!!

If you need a little more help with some math problems you can always PM and I'll try and explain them to you better

I took the NET and got 100% on the math section. If there's anything I can do to help you out, let me know. Really.

Also, have you looked at the NET test company's website? There's a practice test on there that you can buy for something like $20 and it's literally nearly IDENTICAL to the actual NET test itself.

I have the NET book, my test is acutally next week on the 24th so I have a little more time to study. I'll check out the practice tests on the site. Its all coming together a little betternow. My algebra is doing better, I have a few more that I have issues with and I can't get it right.

Here is the questions in the book that I cannot figure out HOW to do them.

3/16 = ? % X 3/4 (A. 20, B. 25, C. 15, D. 10)

The Ratio of 2 to 5 = ? % (A. 10, B. 40, C. 4, D. 0.1)

7 2/5 of x is equal to 74. Solve for x

(A. x=50, B. X=1000, C. X=100, D. X=500)

Those are the three question types I am having trouble with. Educate me PLEASE :bowingpur

OK let me see if I can help!

A trick is to make sure everything is in 100 if you're trying to get percents. For example, "the ratio of 2:5 = ?%", so make a number 100. So the problem would now read "the ratio of 40:100 = ?%", and the answer would be 40/100=40%, answer B. Or if you knew 2/5 = somewhere around 40%, you could have ruled out answers A, C, and D. :)

Another trick is to put the answers back into the equation and solve to see if it's correct. For example, the first problem 3/16 = ?% X 3/4. So let's plug in answer A which is 20% and see if it works:

3/16 = .20 X 3/4

.1875 = .15, so 20% isn't the answer, it has to be higher. So by default it has to be 25% because that's the only other answer they gave us that's higher than 20%, but let's test it just in case.

3/16 = .25 X 3/4

.1875 = .1875 CHECK! So B., 25% is the right answer.

I find this method to be REALLY useful when you need to work FAST and make sure you have the correct answer. I have to say that I plugged in answers to equations on nearly half of the questions on my NET test as I found it the most convenient way to do things.

OK, the last problem says 7 2/5 of x = 74. Here, you could also plug in answers and then solve to see if they're correct. So let's use 500 for starters (answer D). Take 500 and multiply it by .074 (which is 7 2/5 in decimal form with the decimal moved over twice to the left to get a percent) and that would give you 34. So 500 isn't the answer, and we KNOW it has to be higher than 500 because we need the answer to be 74, which is higher than 34. So the answer HAS to be 1000 (answer B). But let's try it just in case so as to check ourselves.

1000 x .074 = 74! Perfect. If your brain works this way, you could have just converted 7 2/5 to 7.4 and then .074 and realized you had to move the decimal over 3 places to get 74 from .074 and thus had to multiply by 1000. But mine doesn't work that way and I always have to write the whole thing out! :)

These are the ways I personally would have solved these equations. :) Easiest way for me to get through the NET was to do it this way and it was easily finishable using these methods in the alotted time!!! Hope this helped.

Also a quick note to EVERYONE who's taking the NET!

This equation literally saved my life:

is/of = %/100

There are A LOT of questions on both the TEAS and the NET involving these types of equations and this ONE short cut (see above) solves it all.

For example: "What is 30% of 40?"...Plug it into the equation!

x/40=30%/100 and then solve for x!

or "12 is what percent of 40?"...PLUG IT IN! :)

12/40=x%/100 and solve for x!

or "12 is 30% of what number?" ...YES, YES! Plug it in!!

12/x=30%/100 and solve for x!

This simple short cut for percent word problems that I learned in like...5th grade or something was a HUGE life saver!

THANK YOU THANK YOU THANK YOU! I got it now. I just took the practice test online and on the Math part I got a 87 which is better than I thought and on the reading I got 58 which is less than the average...UGH! So after I conquer the math I will read the sections about the reading comprehension section. Thank you so much for your help, it has really made a difference.

Of course!!!! Please let me know if you have any other questions.

And I by far agree that the reading section is the hardest part of the NET. It seems SO EASY but then you get your scores back and realize how hard it actually is!

Goodluck to you in your studies :)
