Question

Dau coroana!!! Vă rog cât mai repede posibil​


ordonati descrescator numerele x,y,z,t, stiind ca: x=(-0,27)+(-9/25)-(-3/4)+(-0,34); y=5/8-(-0,274)+(-17/40)-0,085; z=(-7/10)-[-0,8(3)]+(-0,5)-0,7; t=7/25+[-0,5(3)]-[-0,58(3)]-0,84

Answer 1

$x = - \tfrac{27}{100} - \tfrac{9}{25} + \tfrac{3}{4} - \tfrac{34}{100} = \tfrac{ - 27 - 36 + 75 - 34}{100} \\ x = - \tfrac{22}{100} = - 0.22 \\ \\ \\ \\ \\ y = \tfrac{5}{8} + \tfrac{274}{1000} - \tfrac{17}{40} - \tfrac{85}{1000} = \tfrac{625 + 274 - 425 - 85}{100} \\ y = \tfrac{389}{1000} = 0.389 \\ \\ \\ \\ \\ z = - \tfrac{7}{10} + \tfrac{75}{90} - \tfrac{1}{2} - \tfrac{7}{9} = \tfrac{ - 63 + 75 - 45 - 70}{90} \\ z = - \tfrac{103}{90} = - 1.14 \\ \\ \\ \\ \\ t = \tfrac{7}{25} - \tfrac{48}{90} + \tfrac{525}{900} - \tfrac{21}{25} = \tfrac{ - 14}{25} - \tfrac{8}{15} + \tfrac{175}{300} \\ t = \tfrac{ - 168 - 160 + 175}{300} = - \tfrac{51}{100} = - 0.51 \\ \sout{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: } \\\boxed{ \text{ordine \: descrescatoare : }y,x,t,z}$
