## ikshjbdckoj 2 years ago Can someone Please help me. And this is going to take a while so whoever helps me I want and need them to have time because I don't want either one of us rushing.. It's just a lot of algebra problems.

1. mathsmind

ok what are the problems?

2. ikshjbdckoj

okay how many do you want me to give at a time?

3. mathsmind

all of them

4. mathsmind

if u have them on a document send me the document or whatever file format u prefer

5. ikshjbdckoj

okay hold on. It'll take about 3 minutes.

6. mathsmind

ok not to worry i am solving another problem

7. ikshjbdckoj

ok I have a question. like the first problem on my worksheet is a fraction and the only way you can see the fraction is if I draw it. So do you think I should just send it to you regular? And then when I have like fractions I can draw them for you.

8. ikshjbdckoj

This is the first one. What is the sum? $\frac{ 7 }{ 2 }+ \left(\begin{matrix}-3 \\ 5\end{matrix}\right)$

9. mathsmind

whichever way u prefer suit urself i will solve them all

10. mathsmind

you mean

11. ikshjbdckoj

$\frac{ 4 }{ 3 } \frac{ 29 }{ 10 } \frac{ -21 }{ 10 } \frac{ 41 }{ 10 }$

12. mathsmind

$\frac{ 7 }{ 2 }+(\frac{ -3 }{ 5 })$

13. ikshjbdckoj

Yeah I meant that. Sorry

14. mathsmind

$\frac{ 35-6 }{ 10 }=\frac{ 29 }{ 10 }=2.9$

15. ikshjbdckoj

Oh okay. I see. here's my second one. Which property is illustrated by the statement? (4 + 6.1) + 7 = 4 + (6.1 + 7) Associative Property of Addition Inverse Property of Multiplication Commutative Property of Addition Inverse Property of Addition

16. mathsmind

$\frac{ 4 }{ 3 } + \frac{ 29 }{ 10 } +\frac{ -21 }{ 10 } + \frac{ 41 }{ 10 }$

17. mathsmind

is that what you mean

18. mathsmind

why don't u take a picture of that document with ur phone and send me the whole problem sets

19. ikshjbdckoj

Okay I have a i phone but if I take a picture of it with my phone how am I gonna get it to you?

20. mathsmind

well save the picture transfer the picture to ur pc using a cable

21. ikshjbdckoj

okay hold on :)

I don't know how to tell or not :( 30. ikshjbdckoj Do you want to start working on it now? 31. mathsmind hehehe i will highlight them with red color 32. ikshjbdckoj have a question.I know we don't know each other at all. But do you have a i phone? cause if you have a i phone I could send you the pictures off of my phone and that would make it soooo easy!!! 33. mathsmind no don't use any smart phones 34. mathsmind plus i am from the UK not in the state 35. mathsmind those smart phones dulls minds 36. mathsmind its a waste of time 37. ikshjbdckoj they always break!! Mine is broke is some places now :( but anyway okay lets work on this because my teacher is giving me all today to finsish this and if i dont finish it then im gonna fail my first semester of algebra :((((( 38. mathsmind no u won't i will finish the job and explain it for u 39. ikshjbdckoj thank you so much!!! 40. mathsmind if u look at the what is written after (1 point) u'll see the answers they already exists 41. ikshjbdckoj how?? 42. mathsmind 2.
