Which expression would be easier to simplify if you used the associative

rodikova [14]

Answer:

A . 0.85 + (0.15 +(-3)) = -2

B . [(-3)+(-3)]+(-3) = - 9

Step-by-step explanation:

Explanation:-

Associative property with addition

(a+(b+c)) = (a+b) + c

Given 0.85 + (0.15 +(-3)) = (0.85 +0.15)+(-3)

= 1 - 3

= -2

B) Given [(-3)+(-3)]+(-3) = ( (-3)+[( -3)+(-3))]

= ( -3 +[-3-3]

= -3 -6

= -9

Final answer:-

A . 0.85 + (0.15 +(-3)) = -2

B . [(-3)+(-3)]+(-3) = - 9

To figure this out you can do a proportion
34 X
---- = ------
55 100
Then you would cross multiply to get
55x=3400
Next you would divide 3400/55 which would come out to be 61.8181818 which would be your percentage 61.81%
