Question

i have tried many different ways to tackle this problem. and just dont understand. help would be aprreciated... im not trying to cheat answers.


-1/3(8/3) divided by 1 over negative 1/3 minus 8/3 to the second power + 10.

10 points to whoever explains the best and gives correct answer.

Answer 1

-1/3(8/3) divided by 1/(-1/3) - (8/3)^2 +10
Taking sections at a time:-
-1/3(8/3) means -1/3 x 8/3 = -8/9

Next Section
divided by 1 over -1/3 =
1/1 divide -1/3 = 1/1 x -3/1 = -3

Next section
(8/3)2 (8/3 to second power)
8/3 x 8/3 = 64/9

Tidying up
-8/9 divide -3 - 64/9 +10
-8/9 x -1/3 - 64/9 + 10
8/27 - 64/9 + 10
8/27 - 192/27 + 270/27
(8 - 192 + 270)/27
86/27 = 3 5/27

Answer 2

Just follow through the sum, bearing in mind the order of presidence of arithmetic operations (brackets before multiplication etc, I'm sure you know them.

This sum (may) look like: (-8/9)*(-3) -(8/3)^2+10

however, because of the phrasing it may really be (-8/9)*(-1/3-8/3)^2+10. As the wording doesn't tell you anything about possible brackets, you cant really know what it wants.

Answer 3

Do you mean...

[-1/3(8/3)/1] / [(-1/3-8/3)^2+10]
or
[(-1/3(8/3)/1) / ((-1/3-8/3)^2)] +10

I need clearer equation. There are too many ways to interpret your equation.

Answer 4

200 lb is genuine. a sturdy thank you to think of of this is to first understand "a properly mixed" scoop of the seed will comprise a proportional quantity of each and every form of seed. So in case you placed a million pound of the .sixty 5 seed in and 2 kilos of the .40 5 seed. there will be a 2 to a million ratio in choose of the .40 5 seed. which ability 2/3 of the scoops weight comes from the .40 5, and a million/3 from the .sixty 5. you ought to discover the ratio that makes it come out to be .fifty 5 lb on person-friendly. you are able to physique the difficulty like this. .sixty 5 + .45X= .fifty 5 + .55X fixing for X will inform you the ratio of .40 5 lb scoops to .sixty 5 lb scoops. consequently it seems X is a million, which ability for each lb of .sixty 5 seed you like a million lb of .40 5 seed. So in case you have 200 lb of .40 5 seed you elect 200 lb of .sixty 5 seed. in spite of the incontrovertible fact that, if (as an occasion) X got here out to be 2 enable's say then you somewhat'll choose 2 circumstances as many lbs of .40 5 seed for each pound of .sixty 5 seed. it somewhat is slightly in-intensity, yet persons have given you valid algebraic approaches, and that i will additionally vouch and say the respond is 200 lb.

Answer 5
