The cube root of (n increased by 8), or  ∛(n+8), is -0.5, or -1/2.
∛(n+8) = -1/2.  To solve this for n, cube both sides, obtaining n+8 = -1/8.
Eliminate the fraction by mult. all three terms by 8:             8n + 64 = -1
Solving for n:  8n = -65, so that n = -65/8.
 
        
             
        
        
        
Answer:
<em>1 unit left and 7 units up</em>
Step-by-step explanation:
|3 - 2| = |1| = 1
The x-coordinate when from 3 to 2, so it is 1 unit left.
|-4 - 3| = |7| = 7
The y-coordinate when from -4 to 3, so it is 7 units up.
 
        
             
        
        
        
Answer:
p = -2
Step-by-step explanation:
5p - 10 = + 4(1 + 3p)
first get rid of the bracquetes:
5p - 10 = + 4*1 + 4*3p
5p - 10 = + 4 + 12p
subtract left and right of = sign by 5p
5p -5p - 10 = + 4 + 12p -5p
0 - 10 = + 4 + (12p -5p)
subtract left and right of = sign by 4
-10 -4 = 4 -4 + ( 7p )
re arrange
7p + 0 = -14
divide left and right of = sign by 7
7/7 p = -14/7
p = -2
 
        
                    
             
        
        
        
Answer:
If the 21 cm is circumference, the answer would be 35.09.
If the 21 cm is radius, the answer would be 1385.44.
If the 21 cm is diameter, the answer would be 346.36.
 
        
             
        
        
        
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
                ____________________________________
                                          Total Numbers
15 = 3 + 19 + 8 + 32 + x
       ______________
                      5
Cross Multiply
___________
3 + 19 + 8 + 32 +  = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
