Question

a,b {a,b} d p {3,4} b-a=50 a,b= ? help!!!!!​

Answer 1

a/3=b/4=k
A=3k
b=4K
4k-3k=50
1k=50
A=3•50=150
B=4•50=200

Answer 2

Răspuns:  a = 150  si b = 200

Explicație pas cu pas:

[a; b]  d.p. [ 3; 4]  

=>  a/3 = b/4 = k ->  coeficient de proportionalitate

->  a/3 = k =>   a = 3 k

    b/4 = k =>   b = 4 k

___________________

b - a = 50

4 k - 3 k = 50    =>   k = 50

_____________________

a = 3 × 50  =>          a = 150

b = 4 × 50  =>         b = 200
