Answer 1

Answer:

a) 70, 70, 110

b) 20

c) 10, 80, 100

d) 110, 110, 70

Step-by-step explanation:

a)

y+40=110 => y=70

x+110=180 => x=70

x=y=70 => z=110

b)

x+2x+6x=180 => 9x=180 => x=20

c)

y=8x & y+10x= 180 => 8x+10x= 180 => 18x=180 => x=10 => y= 80

z=10x= 100

d)

x=110

z=x=110

y+110=180 => y=180-110=70
