Question

daca x+y+z=46 si a =10 calculeaza;
a)13•x+13•y+13•z+13•a;
B)124+5•x+5•y+5•z-7•a;
c)11•x+11•y+11•z-20•a;
d)576-4•a+6•x+6•y+6•z​

Answer 1

Răspuns:

a). = 13(x+y+z)+13x10=13x46+130=598+130=728

b). =124+5(x+y+z)-7a=124+5x46-7x10=124+5x46-70=284

c).=11(x+y+z)-20x10=11x46-200=506-200=306

d). 576-4x10+6(x+y+z)=576-40+6x46=536+276=812

Answer 2

Răspuns:

a) 13•46+13•10=13•(46+10)=13•56=728

b) 124+5•46-7•10=124+230-70=354-70=284

c) 11•46-20•10=506-200=306

d) 576-4•10+6•46=576-40+276=536+276=812
