Answer:

-\frac{1}{200}

Step-by-step explanation:

\frac{6}{10}×\frac{3}{10}-\frac{2}{10}+\frac{4}{10}

\frac{6}{10}×\frac{3}{10}=\frac{18}{100}

\frac{18}{100}-\frac{2}{10}=-\frac{1}{50}

-\frac{1}{50}+\frac{4}{10}=\frac{1}{200}

A merchant buys a television for $125 and sells it for $75 more.What is the percent of markup?
cestrela7 [59]
Since he sold it for $75 more,

% Mark Up = Mark Up/ Cost Price  x 100%

% Mark Up =   75 / 125 x 100%      =   0.6  x 100% = 60%

Percent Mark Up = 60%
Hope this helps :)

The correct answer is:  [D]:  "  x² – 5x – 24 " .
____________________________________________________
Explanation:
_____________________________________
Given:  " (x + 3)(x – 8) " ; expand :
______________________________________
Note:  (a + b) (c + d) = ac + ad + bc + bd .
_____________________________________
a = x ; 

b = 3 ; 

c = x  

d = 8
_______________________________________

   " (x + 3)(x – 8) " ; 

        =  (x * x)  + ( -8 * x)  + ( 3 * x ) + (3 * -8) ; 

        =  x² + (-8x) + 3x + (-24) ;

         = x² – 8x + 3x – 24 ;

→ Combine the "like terms" :

          – 8x  +  3x  =  – 5x ;

And simplify the expression; 

to get: 

→  " x² – 5x – 24 " ; which is:  Answer choice:  [D]:  " x² – 5x – 24 " .
