Question

2) para x=3 ; y=4 z=5
a) 4 x + 5 y + 3 z =

b) 4x + 3y + 4z =
     6      6     10

c) 3z + 5x - 6y =

d) 6y + 2z + 5x =
     8              3

e) 3z 6x - 2y =
     5   9    4

f) 4y + 4x - 4z =
    8      2

Answer 1

a) 4.3 + 5.4 + 3.5 = 12 + 20 + 15= 47
b)4.3/6 + 3.4/6 + 4.5/10 = 12/6 + 12/6 + 20/10 = 60/30 + 60/30 + 60/30= 180/30= 6
c) 3.5 + 5.3 -6.4 = 15 + 15 - 24 = 30 - 24= 6
d) 6.4/8 + 2.5 + 5.3/3= 24/8 + 10+ 15/3= 72/24 + 240/24 + 120/24= 432/24 = 18
E) Favor verificar o sinal entre 3z e 6x
f) 4.4/8 + 4.3/2 - 4.5 = 16/8 + 12/2 - 20 = 16/8 + 48/8 - 160/8 = -12

Answer 2

Resposta:

a) 4.3 + 5.4 + 3.5 = 12 + 20 + 15= 47

b)4.3/6 + 3.4/6 + 4.5/10 = 12/6 + 12/6 + 20/10 = 60/30 + 60/30 + 60/30= 180/30= 6

c) 3.5 + 5.3 -6.4 = 15 + 15 - 24 = 30 - 24= 6

d) 6.4/8 + 2.5 + 5.3/3= 24/8 + 10+ 15/3= 72/24 + 240/24 + 120/24= 432/24 = 18

E) Favor verificar o sinal entre 3z e 6x

f) 4.4/8 + 4.3/2 - 4.5 = 16/8 + 12/2 - 20 = 16/8 + 48/8 - 160/8 = -12
