20x - 10 + 14x - 19 = 90

x = 3.5

∠DAB = 180 - ( 14x - 19 ) = 150

AD=AE\(\Rightarrow\) triangle ADE is an isosceles triangle. \(\Rightarrow\) angle ADE= angle AED=(180-56)/2=62 degrees

BA || CE \(\Rightarrow\) angle BAD = angle ADE = 62 degrees

BA || CE \(\Rightarrow\) BA || CD and CB || DA by given \(\Rightarrow\)quadrilateral BCDA is a parallelgram

angle BCD = angle BAD = 62 degrees (opposite angles of parallelgram are equals) 

2010 = 2 * 3 * 5 * 67

201 = 3 * 67

Therefore, the amallest positive n =201

201 / 2010 = 1/10 =0.1

assume all female have math degree.1300 out 2000 people have math degree, while 640 of those 2000 people are female. Therefore,the minimum number of males with maths degrees is 1300-640=660

That is incorrect, please explain your answer as well. Thank you!

There will be four points labelled 25.

to paint one house   requires    4 people x 6 hours  =  24 people hours  to paint the house

        if you have only three people     it will take 8 hours      (to get 24 people hours)

It is good that you made your own answer.

I was just a bit put out because you said you were really struggling with the whole topic, not just this question, and I gave you a much more thorough teaching answer then I would normally bother to do.  

But in reality, you were not struggling with the whole topic and were capable of answering by yourself. 

The time I took to give you a full explanation could have been better used.

However, you do not need to feel bad about it, I know you didn't do it on purpose, you were just being a little dramatic.  (in your private message)

Cause that is how you felt at the time.

(it would have been nice to get a point from you though, not that the point itself is significant to me, but the show of gratitude always is)

-6 - -10  =   - 6 + 10   = 10 - 6 =  4

You are shown two points on the line      label one of them  '1'  abd the other  '2'   (it does not matter which one you label what)

     slope is then    (y1-y2)/(x1-x2)    this is the same as   rise / run    

8 hours:

Let's take the LCM of 4 and 3: it's 12. So, since 12 is 3 times 4, we divide (inverse proportions) by 2. So it will take 2 hours for 12 people. Now, we see that we divide by 4 to get to 3. Therefore, we multiply by 4 and get 8.

Is that correct?

:)

4 x^2 + 7 x y - 8 x - 2 y^2 + 11 y - 12
 

I dont even know how you came up with that c**p

Try looking on the general Answers page, rather than selecting this specific question.

As follows:

Can you take it from here?

Sorry, Melody. :( I only read the beginning of your answer, and then decided to come up with my own to see if I could start off of what you did. :) I then read your whole answer and realized they were very similar and yes, your's was explained way more thoroughly. :) I just wanted to see if I could do it by starting off of your well explained answer, since I thought I would learn best that way~ Sorry again, I shouldn't have made another answer. 😢

ok Melody, I do understand. :) I may have assumed something that wasn't true. :( I mean, kenisan could have done it her/himself, but the way of him/her's wording did make it seem like she got the answer randomly from another forum site or something like that. :(
