Question

Află valorile literelor și verifică.
1065:15 + 355: 5 + 355 : 71 +1 1065 : a = 162
[(b - 8 000): 50 + 900] : 250 = 4
​

Answer 1

Răspuns:

1065:15+355:5+355:71+1065:a=162

71+71+5+1065:a=162

147+1065:a= 162

1065:a= 162-147

1065:a=15

15a=1065

a=1065:15

a=71

Verificare :

1065:15+355:5+355:71+1065:71=162

71+71+5+15=162

162=162

__________

[(b-8000):50+900]=4·250

(b-8000):50=1000-900

b-8000=100·50

b=5000+8000

b=13000

verificare:

[(13000-8000):50+900]:250=(5000:50+900):250=1000:250=4
