Question

x/5=y/2=z/3 Sabendo que 3x+y+2z=276​

Answer 1

Resposta:

x = 60  y = 24  z = 36

Explicação passo-a-passo:

x/5 = y/2 = z/3

x/5 = y/2

2x = 5y

x= 5y/2

y/2 = z/3

2z = 3y

z = 3y/2

3x + y + 2z = 276

3(5y/2) + y + 2(3y/2) = 276

15y/2 + y + 6y/2 = 276

15y/2 + 6y/2 + y = 276

21y/2 + y = 276

21y/2 + 2y/2 = 552/2

23y = 552

y = 552/23

y = 24

x = 5.24/2

x = 120/2

x = 60

z = 3.24/2

z = 72/2

z = 36
