I can help also! im on the same thing

9. Bri_Durbin

same test or grade or what?

same grade and same class! i kno most of the answers tho

11. Bri_Durbin

19. amistre64

as long as the responses can conform to the code of conduct for this site .... and not just be handing out answers, i might be swayed

20. Bri_Durbin

oh ok well do you wanna HELP me?

21. Bri_Durbin

Can some one help me with this one Which property is illustrated by the statement? (4 + 6.1) + 7 = 4 + (6.1 + 7) (1 point) Associative Property of Addition Inverse Property of Multiplication Commutative Property of Addition Inverse Property of Addition

22. amistre64

can you narrow it down any?

23. Bri_Durbin

i think that it is A. is that correct?

24. amistre64

it might be, can you tell me why you think it would be A?

25. Bri_Durbin

Because like its all addition so I thought that it would be associative Property of Addition.

it is A

27. amistre64

there are 2 properties on the option list that are very similar Associative and Commutative. Commutative means to change places, and none of the terms changed places Associative means to make new friends (to regroup) The terms were regrouped, so yes; its Associative Addition

28. Bri_Durbin

wahoo i knew it!! =D I feel smart! Ok i have another one.

29. Bri_Durbin

To which subsets of the real numbers does the number 1/3 belong rational numbers irrational numbers whole numbers, integers, rational numbers whole numbers, natural numbers, integers

30. Bri_Durbin

i think that it would be rational because its a fraction...

31. amistre64

correct, its a ratio of numbers, rational

32. Bri_Durbin

YAY! ok What is the algebraic expression for the following word phrase: the product of 5 more than p and 7? (1 point) 5 + p + 7 7(p + 5) 7 • p • 5 p + 5 over 7

33. Bri_Durbin

idk the way its worded confuses me.

34. amistre64

the product of (to multiply); (5 more than p) and (7)

35. Bri_Durbin

but im thinking B because it has addition and multiplication.

36. amistre64

B is good

37. Bri_Durbin

What is the simplified form of the expression square root 1 over 121

38. Bri_Durbin

121 1/11 11 2/242

39. Bri_Durbin

would this one be 11?

40. amistre64

use grouping symbols; square root (1 over 121) a calculator can verify this one. its not 11, but it has 11 in it :)

41. Bri_Durbin

1 over 11

42. amistre64

1/11 is what i would choose yes

43. amistre64

write up a new post for more questions, that way others can have the chance to share :) I have real world work to attend to

44. Bri_Durbin

ok thanks!
