Question

( 3 целых 12 (23 в квадрате ) ) * x+38 = 518

Answer 1

$(3 frac{1}{2} ( frac{2}{3} ^{2} ))*x+ frac{3}{8} = frac{5}{18} \ \ (3 frac{1}{2} ( frac{2}{3} *frac{2}{3} ))*x+ frac{3}{8} = frac{5}{18} \ \ (3 frac{1}{2} * frac{4}{9} )*x+ frac{3}{8} = frac{5}{18} \ \ ( frac{7}{2} * frac{4}{9} )*x+ frac{3}{8} = frac{5}{18} \ \ frac{28}{18} *x = frac{5}{18} - frac{3}{8} \ \ frac{28}{18} *x = frac{40}{144} - frac{54}{144} \ \ frac{28}{18} *x = (- frac{14}{144}) \ \ x=(- frac{14}{144}) :frac{28}{18}$

х= (-14/144) * 18/28
х = (-1/8) * 1/2
х =(-1/16)
