Answer:
The answer is y = 80±
and x = ±
Step-by-step explanation:
We need to solve this system of equations algebraically
y + x = 19 - 
..............................................(1)
x+y = 80 ...............................................................................(2)
Substituting equation (2) in equation (1)
80 = 19 -
-61 =
x = ±
Where i is the imaginary
Then the value of y = 80±
This is the solution to this system of equations
Probablity is (desired outcomes)/(total possible outcomes)
less than 5
therea er 1,2,3,4
4 number
total possible is 6 since 6 faces
probablity is 4/6=2/3
We will call the number of tickets you sell 
and the number your friend sells 
. Given this, we can create the first equation, which is:
- This shows that the number of tickets you sold is equal to the number your friend sold + 14, which symbolizes that you sold 14 more tickets than your friend
We can also create the second equation:
- This shows that the number of tickets you sold along with the number of tickets your friend sold is equal to 58 tickets in total
Thus, our system would be:
Answer:
7 < x < 12
Step-by-step explanation:
To solve this inequality, solve it the same way you do a normal function. Perform the same actions on both sides of the inequality.
