Answer:
4 = 20 + n, where n is the number
Step-by-step explanation:
Here are a few key words to use when converting words to an equation 
"is": =
"more": +
"less": -
"more than", "greater than": >
"less than": <
 
        
                    
             
        
        
        
2/3 of the list = 12
2/3x = 12
x = 12 / (2/3)
x = 12 * 3/2
x = 36/2
x = 18 <=== there are 18 words on the list
        
             
        
        
        
Since the slope is falling, instead of rising, it would be negative. 
Now, on the line, I plotted (0, 2) and (-2, 10).
You would now plug this into the rise/run formula. 
The formula is 

The equation would become, 

 = 

 = 
-4I believe the answer would be 
-4. 
I hope this helps!
 
        
        
        
Answer:
r = 2.55
Step-by-step explanation:
The formula for finding the radius of a circle using the area is r = √A/π
with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).
So the equation should look like this:
r = √(20.4/3.14)
Find the quotient of 20.4/3.14 and round to the nearest tenth
r = √6.5
Find the square root and round to the nearest hundredth
r = 2.55
 
        
             
        
        
        
Answer:
mean=87
median=87
Step-by-step explanation:
mean=sum of test score/number of subject
mean=79+91+93+85+86+88/6
mean=522/6
mean=87
Literal meaning of median is medium.
To find the number which lies in the medium, we must rearrange the number in ascending.
79, 91, 93, 85, 86, 88
79, 85, 86, 88, 91, 93
86+88/2=87
Hope this helps ;) ❤❤❤
