Question

Suma a doua numere este 50 iar cele doua numere sunt direct proportionale cu 4, respectiv 6 Aflati numerele .

Answer 1

a + b = 50
a/4 = b/6 = (a+b)/10 = 50/10 = 5
a = 4x5 = 20
b = 6x5 = 30

Answer 2

[tex]x+y=50 \\ \frac{x}{4} = \frac{y}{6} =k \\ \frac{x}{4}=k=\ \textgreater \ x=4k \\ \frac{y}{6} =k=\ \textgreater \ y=6k \\ 4k+6k=50=\ \textgreater \ 10k=50=\ \textgreater \ k=5 \\ x=4*5=20 \\ y=6*5=30 \\ BlackBook [/tex]
