Since Mars has less mass than Earth, the surface gravity on Mars is less than the surface gravity on Earth. The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.
Answer:
Step-by-step explanation:
3x + 6 = 2x
3x - 2x = -6

Answer:
adults : 0 children: 600
Step-by-step explanation:
x + y = 600
6x+4y = 2400
4×(x + y = 600) = 4x+4y = 2400
(6x+4y = 2400) - (4x+4y = 2400) = x=0
so y=600
