-4x-2y+4x+8y= -12-24
6y= -36
y= -6
-4x-2. (-6)= -12
-4x+12= -12
-4x= -24
x=6
(6, -6)
Answer:
12:02 AM on the next Thursday
Step-by-step explanation:
First we wanna find how many days that is. 154/24. that is 6 and 5/12 days.
5/12 of a day is equal to 10/24, so 10 hours, sice there are 24 hours in a day.
so that's 10 hours and 36 minutes which equals 2:02 pm + 10 hours 12:02 AM on Friday
Now just add the 6 days so 12:02 AM on the next Thursday
The answer is 2.45 x 10^5.
7 x 3.5 = 24.5
Move the decimal place over to the left until you have a number between 1 and 9 before the decimal point.
Add the number of times you moved the decimal point to the exponent (The 4 in the original equation).
2.45 x 10^5.
I hope this helps!
