Question

d) (d - 5x6 + 10 x 5): 5+ 4 x 8 = 42
e) (66 - 3x6 - 16:2) -e = 15:3
f) f: (7 x 9 - 9 x 6) = 60 : 6
g) (9x4: 6 xg) - 5 x 5 = 45:9
h) (96-3x4-5x8) +f-9 x 7 = 13
i) k-(28:4 + 24 : 4) = 8 x 9 - 20:4​

Answer 1

Răspuns:

d) (d-30+50):5+32=42

(d-80):5+32=42

(d-80):5=42-32

d-80=10*5

d-80=50

d=50+80

d=130

e)(66-18-8)-e=5

40-e=5

-e=5-40

-e=-35|(-1)

e=35

f)f:(63-54)=10

f:9=10

f=10*9

f=90

g)(6xg)-25=5

6g-25=5

6g=5+25

g=30:6

g=5

h)(96-12-40)+f-63=13

44+f-63=12

f=12-44+63

f=31

i)k-(7+6)=72-5

k-13=67

k=67+13

k=80
