DATI-MI VA ROG RASPUNS SI EXPLICATIE XX DAU COROANA XX

Answer 1

648= 3 x a
3 x a=648
Take 648 divide by 2 get 224
divide 224 by 2 get 112 multiply by 3 get 336
648 - 336 equals 312
312=s 336=a
s + a = x
312 - 64 + 336 - 64 =
312 -64= 248
336 - 272
x= 336 - 272
336 - 272= 64
64 x 3= 192
so Simone has 192
