In a film, a character is criticized for marrying a woman when he is three times her age. he wittily replies, "ah, but in 25years time i shall only be twiceher age." how old are the man and the woman?

The woman its 25 years old. The man its 50.

Step-by-step explanation:

Let the age of the man (in years) be and the age of the woman (in years) be , right now he is three times her age, so:

We also know that in 25 years, his age, , will be two times the age of hers, , so:

.

Now, of course, the age of each one, in 25 years, will be the same age they got right now plus 25 years;

We can replace this values on our second equation, and get:

Working it a little:

We can replace this value on our first equation:

The woman its 25 years old! We know the man its three times that age, so:

.

The man its 75 years old!

In 25 years she will be 50 and he will be 100, exactly two times her age. :)

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
