What is -9x-(2x/-3) When x equals 7

yuradex [85]

$-9x- \frac{2x}{-3}$

$-9*(7) - \frac{2*7}{-3}$

$9*7 = 63$

$\frac{2*7}{-3} = \frac{14}{-3}$

Apply the fraction rule : $\frac{a}{-b} = - \frac{a}{b}$

$= - \frac{14}{3}$

$-63-( -\frac{14}{3} )$

Apply rule - ( - a) = a

$-63+ \frac{14}{3}$

Convert element to fraction :

$63 = \frac{63}{1}$

$-\frac{63}{1} + \frac{14}{3}$

Find the LCD 1*3 = 3

$- \frac{63*3}{3}+ \frac{14}{3}$

$\frac{-3+63+14}{3} = \frac{-175}{3}$

<span>Apply the fraction rule : $\frac{a}{-b} = - \frac{a}{b}$ </span>

$= - \frac{175}{3}$

hope this helps!

What is the area of the white border?

Lina20 [59]

Answer:

$A_{white} = 119\ cm^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the black area</u>

$A = l * w$

$A = 8\ cm * 2\ cm$

$A = 16\ cm^2$

<u>Step 2: Determine the area of the entire white and black area</u>

$A = l * w$

$A = 9\ cm * 15\ cm$

$A = 135\ cm^2$

<u>Step 3: Determine the difference to just get the white area</u>

$A_{white} = 135\ cm^2 - 16\ cm^2$

$A_{white} = 119\ cm^2$

Answer: $A_{white} = 119\ cm^2$
