o camasa = 170 cm
o bluza =150 cm
doua camasi = 170cm x 2=340cm
trei bluze = 150x3 =450cm
340+450=790cm stofa total
17 . L=986 m b+639 ( c ) =737
a + b =347. b=737-639
b+c=737. b=98 !!!!!
a + b +c =986
347 ( a+b ) + c =986
c = 986-347
c=639 !!!!
a+98 (b ) +639=986
a+737 =986
a=986-737
a=249!!!!
18 . 38+7=45
45:5=9
a=2x9=18
b= 9
c=a-7,c=18-7=11
19 . l=92
L=92x5=460
(92x2)+(460x2)=184+920=1104m. rezultat = 1104
Imi dai coroana ???? , sper ca te-am ajutat !! succes!
