Answer:
37.5
Step-by-step explanation:
16/46 = 20/(20+x)
or, 16(20+x) = 46×20
or, 320 + 16x = 920
or, 16x = 600
or, x = 600/16
 x = 37.5

The greatest common factor between 64 and 24 is 8
Let's divide both terms in the expression by 8 and leave the expression in parenthesis... 
Like this! 
64x -24 

8x - 3
Leave 8 we divided outside the parenthesis 
Now we have this! 
8( 8x - 3) 
This is the distributive property form!
