Question

MEDIA ARITMETICA A 2 NUMERE ESTE 35 .AFLATI NUMERELE STIIND CA ELE SUNT DIRECT PROPORTIONALE CU 1 SI 6

Answer 1

 [tex]m_a=\frac{a+b}{2}=35\;\Rightarrow\;a+b=2\cdot35=70\;;\\ \frac{a}{1}=\frac{b}{6}=\frac{a+b}{1+6}=\frac{70}{7}=10\;;\\ \Rightarrow\;\;a=1\cdot10=\fbox{10}\;\;si\;\;b=6\cdot10=\fbox{60}\;;[/tex]

Answer 2

[a+b]/2=35
⇒a+b=70;
⇒a/1=b/6=k;
⇒a=k;
⇒b=6k;
⇒7k=70⇒k=10;
⇒a=10;
⇒b=60;
