M = mass
So E = mc^2 is
Kinetic energy = mass * speed of light^2
Answer:
HI! I think the answer is 4.
Answer:
1,570
Step-by-step explanation:
10×2=20
20×3=60
30×5=150
40×7=280
50×4=250
60×3=180
70×8=630
Now,
20+60+150+ 280 +250+ 280+ 630=1,570
this is the answer
1. 3,6
2. 5,6
3. 4,5
(branliest will be appreciated and thanks)
5x-2y=3
-5x+4y=9
2y= 12
divide it by 2
y= 6
put y in any equation
5x-2 (6)=3
5x-12=3
5x= 3+12=15
divide by 5
x=3
y= 6
