Answer 1

7) d : 5 = 7  restul < 5
restul = (0, 1, 2, 3, 4)
d : 5 =7 rest 0 ⇒ d = 7×5= 35
d : 5 =7 rest 1 ⇒ d = 7×5 +1 =36
d : 5 = 7 rest 2 ⇒ d = 7×5+2 =37
d : 5 = 7 rest 3 ⇒ d = 7×5 +3 = 38
d : 5 = 7 rest 4 ⇒ d = 7×5 +4 = 39 → deimpartitul

Raspuns:  35, 36, 37, 38, 39 

Answer 2

$D : I = C rest R \\ \\ D = C\times I + R \\ \\ D = 7\times 5 + R \\ \\ D = 35 + R\\ \\ R \in \{0,1,2,3,4\}\Big|+ 35 \\ \\ (35 + R) \in \{35+0, 35+1, 35+2, 35+3, 35+4\} \\ \\ (35+R) \in \{35,36,37,38,39\} \\ \\ \Rightarrow \boxed{ D \in \{35,36,37,38,39\}}$
