Question

247 и 251 пж помогите 10 бпллов

Answer 1

247.
$- x = 15 frac{4}{7} \ x = - 15 frac{4}{7}$

$- x = - 0.8 \ x = 0.8$

$- x = - 4 frac{1}{3} \ x = 4 frac{1}{3}$

$- x = frac{5}{6} - frac{1}{9} \ - x = frac{15}{18} - frac{2}{18} = frac{13}{18} \ x = - frac{13}{18}$

$- x = - 7.2 \ x = 7.2$

$- x = frac{3}{8} + frac{1}{6} \ - x = frac{18}{48} + frac{8}{48} = frac{26}{48} = frac{13}{24} \ x = - frac{13}{24}$

251. точка Е = 5, точка F = 3, точка К = -2, точка L = -4
