Question

1. Află factorul necunoscut:
a x 3 = 27
9 x a = 63
a x 8 = 48
7 x = 42
5x a = 50
8x a = 8
(3 + 4) x a = 56
a x (25 - 17) = 72
(100 - 91) x a = 36
ax (4 + 5) = 45
(1000 - 992) x a = 48
a x (10 - 10) = 0
ax 5 x 5 = 25
2 x 4 x a = 40
ax2x3 = 24
9 x 1 x a= 81
3 xax 2 = 54
axax 8 = 32​

Answer 1

Răspuns:

a=27:3=9

a=63:9=7

a=48:8=6

x= 42:7=6

a=50:5=10

a=8:8=1

7*a=56 => a=56:7= 8

9*a=36 => a=36:9 = 4

a*0=0 => a=0

a*25=25 => a= 25:25=1

8*a=40 => a= 40:8=5

a*6=24 =>a=24:6= 4

9*a=>81 => a=81:9=9

3* a*2=54 => 3*a=54:2= 27 => 3*a= 27 => a= 27:3=9

a*a*8=32

a*a= 32:8=> 4 => 2*2=4
