\(x^2-x\\=x*x-x*1\\=x(x-1)\)

Find the angles of a triangle if the measures of the angles are in the ratio 2x:5x:3x

2x + 3x + 5x=180

10x=180

x=18 degrees,

Therefore the angles are:

18 X 2=36 degrees

18 X 5 =90 degrees

18 X 3=54 degrees

How to solve: 8(10)^x+2=26

First I subtracted 2 from boths sides to get: 8(10)^x=24   good

Then I divided both sides by 8 getting (10)^x=3               good

I don't know what do do after this part.

When the unknown is a power you usually have  to use logs

\((10)^x=3 \\~\\ log(10)^x=log3 \\~\\ xlog(10)=log3\qquad \qquad \mbox{log10=1 when the base is 10} \\~\\ x*1=log3\qquad \\~\\ x=log_{10}3\\~\\ x\approx 0.4771\)

how do you figure out the scale factor of a dilated figure from its original figure?

If a 2 cm side dilates to 6cm then the scale factor will be 6/2 = 3

Does that answer your question ?

scale factor = new length / original length

How do you find beta and theta

Did you look under the bed?

I find that most things can be found under a bed  !!      

im feeling like finding X

3, two negatives make a positive so the equation become -3+6 or just 3

-4 if that is what you mean.

Okay, I found out how to do it, wow. That moment when you figure out that the way that you have been doing things, is all a lie. Thank you so much for your help. I'm gonna facepalm for a while and blame Saxon math lol.

Nice, LambLamb......!!!!!

I'm feeling very \(\sqrt{10}\) today. And you?

(irrelevant side note: these " reCAPTCHA " things are so obnoxious!!)

7x+6-4x = 5x+6-2x

1. Combine like terms

3x+6 = 3x+6

This is an identity. ANY value of x makes the equation true.

Hope this helps!

You should try excercising self control, and patience. It's good for you. (Imagine if everybody reacted the way the first thing that came into their mind was when they get angry?) This planet would be a lot uglier.

Anyways, to answer your math questions, 9/3% = 9/0.03 = 300

8/2.4% = 8/0.024 = 333 1/3 or 333.333333 ...

There were m visitors in an exhibition on the first day and 1200 fewer visitors on the second day. On the third day, the number of visitors was 30% greater than the number of visitors on the second day. What was the average number of visitors over the three days?

1st day  =   m

2nd day  =  m - 1200

3rd day  =  the number the second day plus 30% more = [m - 1200] + .30[m - 1200]   =  (1.30)[m- 1200]

So....we add the attendance over 3 days and divide by 3   and we have

[m + ( m- 1200)  + (1.30)( m - 1200) ]  / 3         we could leave it like this, but let's simplify

[2m - 1200 +  1.30m - 1560]  / 3         combine like terms on the top

[3.3m - 2760] / 3          note that we can write this as :

[3.3m ] / 3   - 2760/3    =

1.1m  -  920

I see where you got confused......I made a slight error in my first post by keeping the "divided by 3"  part in at the last.....I'll edit that out right now.....!!!!!

Does that help???

Okay... so, if the angle forms an acute triangle, the angle is what still must be gained to reach 360^o. For example, it is 30^o more to 360^o in this acute angle, so the angle is 30^o. However, if the angle is a right angle, then it simplifies to how much it is past the last checkpoint, for example, 135^o is 45^o more than 90^o therefore, the resulting angle is 45^o. I am not good with math terms, but I think I get it.

1 - (60/70)=0.142857....

0.142857 X 100=14.29% Discount percentage.

The list price of  a camera was w dollars. Paul bought the camera for $35 less than the list price. If the sales tax was 8 %, how much did paul pay for the camera including the sales tax?

Notice that   8% tax  can be written as  .08

And if he gets the camera for 35 dollars less than list price he spends  (w - 35)  dollars.....and this is before the tax is added.....

So......he pays this price plus 8% of the price in tax......in math terms we have

Price          +          Tax                  =

(w - 35)(1)       +         (w - 35)(.08)       =         [factor out the (x - 35)]

(w - 35) [ 1  + .08]  =

(w - 35) (1.08)

Does that make sense???

Well, if something is about 1/4 the length of another thing with a known length, a good start is to multiply the known length by 1/4.

33.46 * [about] 1/4 = [about] 8.365

So, if I have an angle, say it's 135o, that simplified would be 45o right? But if I have an angle, say 330o, it simplifies to 30o rather than 60o? Why?

Here is a page with some pretty and interactive diagrams (if you scroll down a bit) that may help you.

inequalities are not my expertise but here's my shot at it:

$14 - 30%($14) > $35

because $9.80 > $35 is true.

I'm not sure if this is what you're asking for ...
