Question

Vă rog!!!!! dau coroană!!!!​

Answer 1

Răspuns:

a)

x = 40 : 10

x = 4

V : 10 × 4 = 40

b)

x = 21 : 7

x = 3

V : - 7 × 3 = 21

c)

x = 48 : 16

x = 3

V : 16 × 3 = 48

d)

x = -3

V = 9 x ( - 3 ) + 27 = 0

e)

x = 5

V : - 3 × 5 = -15

f)

x=2

V: - 2 × 2 + 7 = -4 + 7 = 3

g)

x = - 2

V : 22 × (-2) + 44 = 0

h)

x = 6

V : 11 × 6 + 29 = 95

i)

x = 4

V : -18 + 6×4 = 6

j)

x = 3

V : -3 × 7 = - 23

k)

x = 7

V : 4 × ( 7 - 7 ) = 4 × 0 = 0

l)

x = 3

V : - 3 ( 3 + 6 ) = 6
