Answer 1

Răspuns:

41.526+713.806= 755.332

755.332 - (a+135408) =245.132

755.332-245.132=a+135.408

755.332 - 245.132 - 135.408 = a

a=374.792

(51.432-b) = 150.100 - (113.826 - 39.712)

51.432 - b = 150.100 - (113.826 - 39.712)

51.432 - [150.100-(113.826-39.712)]= b

b=51.432 -(150.100-74114)

b=51.432-75.986

b= - 24.554

800.500 -625.912 = 174.588

174.588 + c - 17.590 = 357.539

174.588 + c = 357.539 + 17.590

c = 375.129 - 174.588

c = 200.541
