Question

X/5=b/2,5=y/15; x+b+y=9 proporciones

Answer 1

Explicación paso a paso:

x/5 = b/2,5 = y/15

x + b + y/5 +2,5+ 15 = x + b + y/22,5 = 9/22,5

x/5 = 9/22,5

22,5x = 5.9

x = 45 : 22,5

x = 2

b/2,5 = 9/22,5

22,5b = 9 . 2,5

b = 22,5 : 22,5

b = 1

y/ 15 = 9/ 22,5

22,5y = 9 . 15

y = 135 : 22,5

y = 6
