2x+ y = -4 5x + 3y = -6
y= -4 -2x
substitute y=-4-2x into 5x+3y=-6
5x + 3(-4-2x) = -6
5x -12 -6x =-6
-x=6
x=-6
sub x=-6 into 2x+y=-4
-12 + y = -4
y=8
x=-6 and y=8
We must solve <span>2/5 ≥ w -3/5. Note that w is already +, so leave it where it now is. Add 3/5 to both sides of this inequality:
2/5 + 3/5 </span>≥ w - 3/5 + 3/5
Then: 1 ≥ w, or w ≤ 1 (answer)

Answer:
25748 km
Step-by-step explanation:
The distance at which astronauts travel can be obtained by calculating the Circumference of the circle.
Circumference of a circle = 2πr ; π = 3.14
Radius = 4100 km
Circumference of a circle = 2 * 3.14 * 4100
Circumference of the circle = 25748 km
Hence, astronauts travel a distance of 25748 km
