x=4. y=-3

Step-by-step explanation:

from equation 2

5x+3y=11..,.........2

3y=11-5x

y=11-5x/3............3

subtitute the value of y into equation 1

6x-y=27

6x-(11-5x)/3=27

6x-11+5x/3=27

lcm =3

multiplying through by 3

3(6x)-11+5x=3(27)

18x-11+5x=81

18x+5x=81+11

23x=92

x=4

when x= 4

subtitute x into equation 3

y=11-5(4)/3

y=11-20/3

y=-9/3

y=-3

x,y= 4&-3

Is 55000 mg greater than, less than, or equal to 2 kg?
seraphim [82]
1 kg = 1,000,000 mg

55,000 mg = 55,000/1,000,000 = 0.055 kg

0.055 kg < 2 kg

so  55,000 mg < 2 kg
