## jameshorton one year ago Which is an example of an algebraic expression? A. g > 14 B. b + 32 C. m – 37 < 52 D. x + 4 = 13

1. anonymous

b

2. jameshorton

thanks

3. anonymous

np

4. anonymous

hey im only in 6th grade so plz dont ask me for any 7th or up questions ok

5. jameshorton

6. jameshorton

what school you go to

7. itsbribro

i'm in 9th if ya'll need help i can help you both maybe lol

Choose exactly two answers that are correct. 3. (3 pt) Which statement is true according to the order of operations? Choose exactly two answers that are correct. A. (11 + 3) • 2 = 14 • 2 = 28 B. 6 + 10 ÷ 2 = 6 + 5 = 11 C. 5 + (9 • 2) = 14 • 2 = 28 D. 8 – 4 ÷ 2 = 4 ÷ 2 = 2

umm if you check my profile out it says

10. itsbribro

B and C

11. anonymous

ya B and C

12. jameshorton

Evaluate. (5 • 8 – 12)(36 ÷ 9 • 4)

13. itsbribro

try working it out PEMDAS

14. anonymous

or please excuse my dear aunt sally

15. anonymous

gtg

16. itsbribro

so what would be the first step?

17. itsbribro

@jameshorton

18. jameshorton

divide

19. itsbribro

Parenthesis Exponents Multiply Divide Add Subtract

20. jameshorton

parenthesis

21. itsbribro

so we would work out whats in the parenthesis first lets work from left to right so....

22. itsbribro

$(5\times8-12)(36\div9\times4)$ whats 5 times 8

23. itsbribro

40 right?

24. itsbribro

$(40-12)(36\div9\times4)$ so whats 40-12

25. jameshorton

28

26. itsbribro

good

27. itsbribro

now whats 36 divided by 9

28. itsbribro

how many times does 9 go into 36

29. jameshorton

0.25

30. itsbribro

no 9 goes into 36, 4 times

31. anonymous

32. itsbribro

so whats 4 times 4

33. jameshorton

16

34. itsbribro

okay now you have 28*16=

35. jameshorton

448

36. itsbribro

yes :) good job

37. jameshorton

Which options could be the next step in simplifying this expression? 15 + (5 + 21) Choose exactly two answers that are correct. A. 15 + 26 (use order of operations) B. 36 + 20 (use the commutative property) C. 20 + 36 (use the distributive property) D. 20 + 21 (use the associative property)

38. itsbribro

i think A and D

39. itsbribro

anything else?

40. jameshorton

yep

41. jameshorton

(3 pt) Which property does the statement illustrate? Column A Column B 1. (n + 6) • 7 = 7 • (n + 6) 2. 3 • (4 • 9) = (3 • 4) • 9 3. (2x • 5y) • 8 = 2x • (5y • 8) 4. 5 • 3 = 3 • 5 A. commutative property of multiplication B. associative property of multiplication

42. jameshorton

@dan815

43. itsbribro

i'm confused sorry lol

44. jameshorton

column b is post to be a and b

45. jameshorton

then you pick which one is accosicative or commutative

46. MikeyMaximum

Are these multiple questions?

47. itsbribro

nvm i got it lol

48. MikeyMaximum

Because if they are then that would make things 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000x easier for me

49. jameshorton

do you know it

50. MikeyMaximum

yeah if they are all multiple questions
