518 + 251 ≈ 520 + 250 ≈ 770
1 hour = 60 minutes
1 minute = 60 seconds.
Saturn: 10 hours 39 minutes and 24 seconds.
Convert hours to minutes: 10 hours x 60 minutes per hour = 600 minutes.
Convert seconds to minutes: 24 seconds / 60 seconds per minute = 0.4 minutes.
Total time for Saturn : 600 minutes + 39 minutes + 0.4 minutes = 639.4 minutes
Answer(-5.0) and (0,-3)
Step-by-step explanation:
Let's multiply the first equation by 3. (As you can see y's coefficient in the first one is 1 and in the second one is -3 , we will multiply the first equation by 3 so when we add the equations their sum will be 0)
Now let's add this new equation and our second equation.
We found x=-3
Now let's plug x's value in one of the equations to find y's value.
So we found y=5
Solution ;
(-3, 5)
