a)-11.2
b)3.2
c)11.2
d)-3.2
11) What is the opposite of
12)
13)
14)

 (10) 3.2   (11) option 2   (12) option 4  

               (13) Distributive  (14) Associative

Step-by-step explanation:

10) "Absolute value" makes the number positive.

       - |-4| + |-7.2|

   =  -  4  +  7.2

   =       3.2

11) "Opposite" changes the sign.

    the opposite of       is    

12) Reciprocal means "flip" the fraction

     the reciprocal of         is    

13) a(b + c) = ab + ac    is the Distributive Property

 =  

 =  

14) a · (b · c) = (a · b) · c     is the Associative Property

  =

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
