shusha [124]3 years ago
8 0

Answer:

4⋅(a⋅2)  

2⋅(4⋅a)

8a

Step-by-step explanation:

(4⋅a)⋅2


4⋅(a⋅2)  This is the same by the  associative property of multiplication


2⋅(4⋅a)  This is the same by the  associative property of multiplication and the communicative property of multiplication


4⋅2⋅a⋅2   This brings in an extra 2 so it is not the same.


8a    4*2 = 8 so this is the same


4⋅2+a⋅2  This is the not the same   8+2a  is not the same as 8a

R/3+2=21 solve for r
olchik [2.2K]

Answer:

r=63

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    r/3-(21)=0             r

Simplify   —

           3

r    

 — -  21  = 0

 3     2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         21     21 • 3

   21 =  ——  =  ——————

         1        3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
