Associative property is dealing with parentahsees and orders
it is
a(bc)=(ab)c and
a+(b+c)=(a+b)+c
so we want the multiplication one
given
(10)(5x)(7)
we can arragnge these a number of ways (we should use commutative property, but whatever)
first one works, the 7 was moved to front
2nd is wrong, that is a wierd version of the distributive
3rd is right, 5x was moved to the front
4th is wack, no bueno
answer is 1st and 3rd options
[Ne] 3s^2 3p^2. is the correct answer :)
2.18 that will be ur answer
Answer:
1st club- 15x +20 Rations- 10x +40 After 4 months the clubs cost the same of $80. The Rations would be a better choice for 6 months.
Step-by-step explanation: 15 would be x because it is per month and you would add a $20 fee each month. For Rations 10 would be x because it is per month and you would add a $40 fee. If you put 15x +20 = 10x +40 (first subtract 10x from both sides and then you would get 5x then subtract 40 -20 and get 20, divide that by 5x and x = 4). 15 times 6 + 20 = 110, while 10 times 6 + 40 = 100 so that means rations would be the better choice
