6 0

Step-by-step explanation:

2x+3y=23 2x+3.7=23 2×1 + 3×7 = 23

3y= 23 2×+21= 23 2 + 21 = 23

23÷3 = 7 2x= 23-21

y=7 2x= 2

x= 1

5x+3y=17 5×4+3y=17

5x=17+3 20+3y=17

5×=20 20=17+3y

14÷5 = 4 20=20+y

x=4 y=20-20

y=0

The Weight On Earth Compared To Some Rando Planet... pls help
earnstyle [38]

Answer:

if your talking about the earth i dont know because no one have ever compared some random planet and earths weight

Step-by-step explanation:

That’s because the planets weigh different amounts, and therefore the force of gravity is different from planet to planet. For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That’s because Mercury weighs less than Earth, and therefore its gravity would pull less on your body.

nikklg [1K]
6(2x-8y=-24)
-2 (6x+4y=68)
12x-48y=-144
-12x-8y=-136
-56y=-280

-280÷-56=5
y=5

2x-8 (5)=-24

×=8


y=5
x=8
