It keeps the planets in orbit.
Inertia is what keeps an object moving (in the same direction). Gravity is the pull of an object to another.
The planets have reached the perfect medium to where inertia keeps the planets moving (instead of remaining completely still in space), and gravity pulls them toward the sun so that they move around it instead of moving straight past it or straight into it.
This is also true about the Earth and the moon.
This is also true with satellites in orbit.
Answer:
x<10
Step-by-step explanation:
First, we want to move all of our like terms to one side. In the inequality, the variable x on one side and our whole numbers on the other.
To do this you have to cancel out 0.5x on the right side. So you need to subtract 0.5 from both sides.
This leaves you with 15+x<25. Subtract 15 from both sides which leaves you with x<10
Hope this helps :)

Answer:
26.25 cm²
Step-by-step explanation:
The area of the shaded part is the area of the shaded triangle subtract the area of the white triangle.
Since the triangles are similar then the ratios of corresponding sides are equal.
let the height of the white triangle be h, then
= 
( cross- multiply )
12h = 90 ( divide both sides by 12 )
h = 7.5
shaded area = 
× 12 × 10 - × 9 × 7.5 = 60 - 33.75 = 26.25 cm²
