The answer is A.
If you divide 4 into all of the answers the only answer that will give you a whole number is 36. example 36/4 = 9
We need the exact value of
to find a proper solution, but a general one can still be found. Subtracting the first equation from the second gives
Plug this into either equation and you get
(It's guaranteed that
in this case because that already corresponds to
.)
Answer:
odd

Answer:
The answer would be D, because it all depend on the quantity.
Step-by-step explanation:
Mary = 3x
Seth = X
If we know that Mary is three times older than Seth, we can set this up into an equation.
3x + x = 76
Now, we can simplify on the left side by adding the Xs together.
4x = 76
X = 19
Therefore, Seth is 19 years old and Mary is 57 years old.
