## supercait10 one year ago 1. If Q=2, Evaluate (34 + 18. q) - (5q + 7) A. 38 B. 79 C. 31 D. 21

1. anonymous

$(34+18\times 2)-(5\times 2+7)$is a better start

2. anonymous

then maybe a calclulator

3. anonymous

actually get none of the above could there be a typo there?

4. supercait10

nope that's the choices

5. anonymous

can you post a screenshot of the question?

6. anonymous

maybe i read "18.q" wrong not really clear there

7. supercait10

yea i'll get a screenshot hold on

8. anonymous

ok

9. supercait10

the last one

10. triciaal

why is this same question posted again?

11. supercait10

Because my teacher gave me a second chance at this question and he said if I couldn't figure it out after five tries he said I can ask for help so I am

12. anonymous

Ah 5 to the power of q, that means the following $5^2 = (5)(5) =25$

13. anonymous

oooh !!

14. anonymous

nothing like the equation editor

15. triciaal

16. anonymous

Please use "^" to indicate to the power of next time :)

17. supercait10

i just posted a file showing the test look at it to understand it

18. anonymous

$(34+18\times 2)-(5^ 2+7)$

19. anonymous

i guess you are supposed to be practising the "order 'o operations" right?

20. anonymous

you know what to do first?

21. supercait10

yup now starting Algebra and haha no my weakest link in school is math I barley passed Math last year so this is beyond me I better understand History then i do math

22. anonymous

square first

23. anonymous

i.e. compute $$5^2=5\times 5$$ don't think too hard here

24. anonymous

what do you get?

25. supercait10

hold on had to get a drink

26. anonymous

yeah i need one too maybe some bulleit rye

27. supercait10

lol maybe

28. anonymous

did you manage to compute $$5\times 5$$ yet?

29. supercait10

yea

30. anonymous

care to share it with the class?

31. supercait10

yea

32. anonymous

...

33. supercait10

25

34. anonymous

whew

35. anonymous

so now $(34+18\times 2)-(5^ 2+7)=(34+18\times 2)-(25+7)$

36. anonymous

now lets do the multiplication $$18\times 2=?$$

37. supercait10

36

38. anonymous

ok so now we are at $(34+36)-(25+7)$ add in each parentheses what do you get?

39. supercait10

(34 + 36 = 70) (25 + 7 = 32) all together = 102

40. anonymous

there is no such mathematical operation as "all together" is there?

41. anonymous

you should be looking at $70-32$

42. supercait10

i'm tired so I'm really not paying attention to what I type

43. anonymous

then go to bed and do this arithmetic some other day

44. supercait10

i can't I have to have this submitted by 11:30 tonight or I fail it
