Answer:
the first problem has infinite solutions, the second has one, and the third also has infinite solutions!
Z = 0.43Y + 12; Z = 28
28 = 0.43Y + 12; insert value of Z
16 = 0.43Y; subtract 12 from both sides
37.21 = Y; divide both sides by 0.43; rounded to nearest hundredth
Answer:
$2
Step-by-step explanation:
Total money Shania was having = $20.
After buying raffle tickets she was having a total of $6.
Thus ,
The money she spent on the raffle tickets = Money she was having initially -
Money she was having after
purchasing tickets .
= $20 - $6
= $14.
Thus She spent a total of $14 on tickets .
Now , number of tickets she bought = 7.
So, cost of each ticket = 
= 
= $2.
Thus , each ticket costs $2 for Shania.
Okay to the first number in the ordered pair is the x and the second is the y. So (x,y) when you put a dot on the coordinate plane such as (2,3), you have to go the the horizontal line which is x and go over right 2 spaces(depending on how many numbers is one space) then go up 3. Do that same thing for each of the order pairs. Eventually you will have 4 dots. Connect those dots then you will have the quadrilateral. I hope this helps you!
