Answer 1

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

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

Explanation:

Explanation:-

Associative property with addition

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

A)

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
