I believe it's D, assuming "a" is a variable. This is because you multiply -16 by 4 to make 3/4a into 3a. The problem is now 3a<-64. Then you divide -64 by 3, which gets you -21.3 or -21 1/3. Now it is a<-21 1/3

188 to 42 what is the percent change
Mekhanik [1.2K]

Answer:

Step-by-step explanation:

so we are gonna have a percent decrease because it went from 188 to 42

decrease = (original number - new number) / (original number ) * 100

                = (188 - 42) / (188) * 100

                = (146 / 188) * 100

                = 0.7766 * 100

                = 77.66% decrease....not sure if u need ur answer rounded to the nearest percent or not....if so, its a 78% decrease

x=-b±root D/2a

x=-6+4root2/2     ,    x = -6-4root2/2

simplify you get the least form...

What is the median of 26, 30, 24, 32, 32, 31, 27, and 29? 32 29 30 29.5?
aalyn [17]
First put both in other 
24,26,27,30,31,32,32 = 30
29,29,29.5,30,32  =29.5

add them together 
=59.5

or if your question is all the numbers together 
24,26,27,29.5,29,29,30,30,31,32,32,32= 29+30
= 29.9
