If you make a list of the driving speed, 60,50,50,40,40,30,30,20,20,10 you notice a patern, To avoid any heavy adding and multpling knowing it 

                                                            +10,20,20,30,30,                                                           equals 5 70's is helpful.  To find the average 

                                                              70,70,70,70,70                                                            you need to add all 10 numbers up and then divide it by 10.  We already know tha t divided by 5 it equals 70 so 70 divided by 2 is 35.  So 35 is our answer

I'm not sure why you are so bitter and toxic online.  I'm sure your a nicer person in real life.  But how exactly was I supposed to know this rule?  Nobody else seems to know it.  Is it even a rule? 

I don't know, Take a guess!

Yup thats it, its a lot harder than algbera 

Thank you!

Here it is in latex. Rationalize the denominator of \(\displaystyle \frac{1}{\sqrt[3]{3} - \sqrt[3]{2}}\). With your answer in the form \(\displaystyle \frac{\sqrt[3]{A} + \sqrt[3]{B} + \sqrt[3]{C}}{D}\), and the fraction in lowest terms, what is A + B + C + D?

When copy and pasting things with latex you need to paste it in the search bar copy it then post it in the question because otherwise the latex doesn't show up and then nobody can help you.

Thank you for the help!

I did!  I have a lot of homework and over the past week these are the ones I needed help with.  I posted them all in the same post because I couldn't figure them out and the only responses I got was the guest giving me rong answers.

Thank you!

The sum of all angles in a pentagon is 540, so wecan use that to find out the missing angle. 98+98+125+108=429, 540-429=111.  

Now we have 2x+11=111

Subract 11 from both sides 2x=100

Divde both sides by 2 x=50

Now for y, since the line is straight the single side will measure 180 degrees.  Subtract 111 from 180 and you get 69.  

Now we have y+8=69

subtract 8 from btoh sides and you get y=61

So now we have X = 50 and Y = 61

If you have any questions feel free to ask

Haha very funny, and incorrect

No problem! Have a nice day!
