Question

7. Dacă:
a = 45 : 9 x 8 - 20 + 2 x 9;
b = (6 x 8 - 48) x 9 + 63 :9;
c = 32 - 6 x 4 + 17
Calculaţi: a +b + c​

Answer 1

Răspuns:

Explicație pas cu pas:

a = 45 : 9 × 8 - 20 + 2 × 9

a = 5 × 8 - 20 + 18

a = 40 - 20 + 18

a = 20 + 18

a = 38

___________________

b = ( 6 × 8 - 48 ) × 9 + 63 : 9

b = ( 48 - 48) × 9 + 7

b = 0 × 9 + 7

b = 0 + 7

b = 7

________________

c = 32 - 6 × 4 + 17

c = 32 - 24 + 17

c = 8 + 17

c = 25

_____________________

a + b + c = 38 + 7 + 25 = 45 + 25 = 70
