Question

5. Calculează: 3a + 3b + c, știind că:
a = (6 + 6:6+2 - 4:4) x 2;
b = (22 - 16:4 + 18:3): 4;
C = 4 + 2 x 24 : 6 + 32 : 4.​

Answer 1

Răspuns:

a = (6 + 6:6+2 - 4:4) x 2

a=(6+1+2-1)X2

a=8x2

a=16

b = (22 - 16:4 + 18:3): 4

b=(22-4+6):4

b=(18+6):4

b=24:4

b=6

C = 4 + 2 x 24 : 6 + 32 : 4.

c=4+48:6+8

c=4+8+8

c=12+8

c=20

3x16+3x6+20=

48+18+20=

66+20=88
