Question

Buna, am nevoie de ajutor.1. (40:5+16):a=9:3 2. (40:5+b):=9:3 3. (40:c+16) :8=9:3 4. (e-64:8+6X4) :5=5 5. (d:5 + 16) :8=9:3 6. (9-64:8+6xf) :5=5 7. (9-64:g+6x4) :5=5 8. (9-64:8+6x4) :h=5

Answer 1

1)(40:5+16):a=9:3
(8+16):a=3
24:a=3
a=24:3
a=8

3) (40:c+16):8=9:3
(40:c+16):8=3
40:c+16=3x8
40:c+16=24
40:c=24-16
40:c=8
c=40:8
c=5

4)(e-64:8+6x4):5=5
e-8+24=5x5
e-8+24=25
e-8=25-24
e-8=1
e=1+8
e=9

5)(d:5+16):8=9:3
(d:5+16):8=3
d:5+16=3x8
d:5+16=24
d:5=24-16
d:5=8
d=8x5
d=40

6)(9-64:8+6xf):5=5
(9-8+6xf)=5x5
1+6xf=25
6xf=25-1
6xf=24
f=24:6
f=4

7)(9-64:g+6x4):5=5
9-64:g+24=5x5
9-64:g+24=25
9-64:g=25-24
9-64:g=1
64:g=9-1
64:g=8
g=64:8
g=8

8)(9-64:8+6x4):h=5
(9-8+24):h=5
(1+24):h=5
25:h=5
h=25:5
h=5

Mult succes la scoală
la ex2 ai uitat să pui o cifră după împărțire si de aceea nu l - am rezolvat
