Va rog!Urrrrrrrrrrrrrrrgggggggeeeeennnnnttttttt!

Answer 1

2)
(13,4 - x) * 5 = 39
13,4 -x = 39:5
x = 13,4 - 7,8 = 5,6

3) 6 baieti ....... 24%
     x elevi ......... 100%

x = (6 * 100%) : 24%
x = 600 : 24 = 25 elevi

4)
10 km ...................... 15 min
x km ........................  3 * 60 min

x = (10 * 3 * 60)/15 = 120 km

5)
Volumul bazinului este: L*l*h = 0,6 m * 0,4 m * 0,5 m = 0.12 m³ = 120 l
120 : 10 = 12 galeti
