Question

2. Se dau numerele: 1. a = 9 b = a x 2 c= b :3 Calculează: a+b+c, a×c-b, b:c×a​

Answer 1

b = a x 2 = 9 x 2 = 18

c = b:3 = 18:3 = 6

a+b+c = 9+18+6 = 15+18 = 33

axc-b = 9x6-18 = 54 - 18 = 36

b:cxa = 18:6x9 = 3x9 = 27  

Answer 2

a=9
b=a x 2=9x2=18
c=b:3=18:3=6
a) a+b+c
9+18+6=33
b)a x c-b
9x6-18
54-18=36
c)b:c x a
18:6x9
3x9=27.
