Answer:

m =   - \frac{ \frac{t}{b} +  \frac{t}{r}  }{1 -  \frac{1}{v} }

Step-by-step explanation:

\frac{m}{v}  -  \frac{t}{b}  = m -  \frac{t}{r}  \\  \frac{m}{v}  -  \frac{t}{b}  +  \frac{t}{r} = m \\  -  \frac{t}{b}   +  \frac{t}{r}  = m -   \frac{m}{v}  \\  -  \frac{t}{b}  +  \frac{t}{r}  = m(1 -  \frac{1}{v} ) \\    - \frac{t}{b}  +  \frac{t}{r}  =  \frac{m( 1 -  \frac{1}{v})  }{(1 -  \frac{1}{v}) }  \\    - \frac{ \frac{t}{b}  +  \frac{t}{r} }{1 - ( \frac{1}{v} ) }  = m

The mean of five numbers 3,7,9,12, and x is 8. Find the value of x
jeyben [28]
Answer:  " x = 9 "  .
____________________________________
Explanation:
____________________________________
To calculate the mean:
____________________________________
The mean = 

     {the sum of all the values in the number set} ÷ 

     {the number of values in the data set} ;
____________________________________
 To solve for "x" ;
____________________________________
Given that the "mean" is:  "8" ;
____________________________________
            8  =  { 3 + 7 + 9 + 12 + x }  /  5  ;
____________________________________ 
    ↔  { 3 + 7 + 9 + 12 + x }  /  5   =  8  ;
____________________________________
            →  { 3 + 7 + 9 + 12 + x }  = 8 * 5  ;
____________________________________
            →  { 31 + x } = 40  ;
____________________________________
            ↔   x + 31  = 40  ;
____________________________________
       Subtract "31" from EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________________
            →   x + 31 − 31  =  40 − 31  ;

                       →  x = 9  .
