How old would a person born in 25 BC be on their birthday in AD 25?
djyliett [7]

Answer:

50 years old

Step-by-step explanation:

The BC/AD time line is like a number line: the negative side of 0, the numbers move backwards; and the positive side of 0 moves normally.  If you have -25, then move to +25, you have just moved 50 places.

Hope this helps :)

Solve the equation 12x+6y= 24 for x.
velikii [3]

Answer: x = -1/2y + 2

Step-by-step explanation:

12x + 6y = 24  To solve for x  first start by subtracting 6y from both sides

      - 6y    -6y

12x =  24 - 6y    Now divide each side by 12

x= 2 - 1/2y

Suppose a standard twelve-hour clock now shows a time of 10:45 what time will the clock show in a 100 hour from now
o-na [289]
It should show 2:45. You can use 12 hr increments to get you back to 10:45 and 12 goes into 100 nine times bringing it to 96. Because of that you have 4 more hours to add to 10:45 and that brings you to 2:45.
