Answer:
Step-by-step explanation:
As 2 and 7 are the only prime divisors of both and we know that both can be written as:
Where is the set of all natural numbers adding the zero (careful because this part is important as I'll explain next).
We also know that 14 divides both numbers and that is actually the greatest common divisor between them. So we can rewrite a and b as follows:
Why do I write them like this? Because this way is easier to observe that if and were both greater than zero, then 28 would divide both hence 14 wouldn't be their g.c.d.. Likewise, if and were both greater than zero, then 98 would divide both and once again, 14 wouldn't be their g.c.d.
So either of them has to be equal to zero. And then we have that
All we have left to do is find the possible values for and so that and that only happens if and
Answer:
1/6
Step-by-step explanation:
because there is only one number 3 there is a 1/6 chance of you getting a 3
Answer: 50x=15000, and x>0
Step-by-step explanation:
Let the number of adult tickets be x .
then the number of children's tickets =3x
Since the ballpark charges $20 for each adult ticket and $10 for each child's ticket.
Therefore total sales on Wednesday=20x+10(3x)
=20x+30x=50x
Since the ballpark made a total of $15,000 from ticket sales at Wednesday's game.
⇒The required equation must be 50x=15000, and x>0
