Question

x/7=y/5=z/11 , x+y+z=138 x,y,z
DAU COROANA ! VA ROG !​

Answer 1

Răspuns:

x=7k

y=5k

z=11k

x+Y+Z=138

7K+5K+11K=138

23K=138

K=6

X=6X7=42

Y=5X6=30

Z=11X6=66

SPER CA TE-AM AJUTAT!

Answer 2

$\frac{x}{7} = \frac{y}{5} = \frac{z}{11} = \frac{x + y + z}{7 + 5 + 11} = \frac{138}{23 } = \frac{6}{1}$

$\frac{x}{7} = \frac{6}{1}$

x=6×7

x=42

$\frac{y}{5} = \frac{6}{1}$

y=5×6

y=30

$\frac{z}{11} = \frac{6}{1}$

z=6×11

z=66
