Answer:

$\frac{-7}{24}$ =r

Step-by-step explanation:

3÷8=r+2÷3

$\frac{3}{8}$ =r+ $\frac{2}{3}$

$\frac{3}{8}$ - $\frac{2}{3}$ =r

(make the denominators same)(LCM of 8 and 3=24)

$\frac{3}{8}$ ( $\frac{3}{3}$ )+ $\frac{2}{3}$ ( $\frac{8}{8}$ )=r

$\frac{9}{24}$ - $\frac{16}{24}$ =r

$\frac{9-16}{24}$ =r

$\frac{-7}{24}$ =r

erik [133]

Answer:

x = 41

Step-by-step explanation:

$\because \angle 1 \:\&\: \angle 2 \: are \: supplementary\\\therefore \angle 1 + \angle 2= 180°\\\therefore 3x°+ (2x-25)°= 180°\\\therefore 5x°-25°= 180°\\\therefore 5x°= 180°+ 25°\\\therefore 5x°= 205°\\\therefore x = \frac{205}{5}\\\huge \purple{\boxed {\therefore x = 41}}$
