Numere zecimale

Post by miruna.lazar »

Suma a doua numere este 10 , 5 . Daca unul din ele este cu 0, 7 mai mare decat celalalt , sa se afle numerele.

Ip. a + b = 10.5
a = b + 0.7

Cc. a=? b=?

Rz. 2b + 0.7 = 10.5
2b = 9.8
b= 4.9
a = 5.6
In all this world there is only one pure and magic thing... and it is called PURPLE!
