8.Se stie ca a+b+c=23s x=9
Dau coroana!!!!
si inca cateva..
b.2013-(53•a+53•b+53•c+10•x)
d.424-21•x+3•a+3•b+3•c
f.3147-10•x-(100•a+100•b+100•c)
​

Answer 1

Răspuns:

a) 14 (a+b+c+x) =14(23+9) =14×32=448

b)2013-(53(a+b+c)+10×x)=2013 -(53×23+10×9)=2013-53×23-90=704

c)349+6(a+b+c)-12×9=349 +6×23-12×9=379

d)424-21×9+3(a+b+c)= 424-21×9+3×23=304

e)7(a+b+c)-10×9=7×23-90=71

f)3147 -10×9-100(a+b+c)=3147-90-100x23=757
