There is a total of $35,000 worth of prizes being given out for 5,000 tickets. We can find the expected value for each ticket by dividing 35,000/5,000. This equals $7.00.
Answer:
(1,2)
y=2
x=1
Step-by-step explanation:
x+y=3
3x+5y=13
solve the equation
x=3-y
3x+5y=13
substitute the value of x into an equation
3(3-y)+5y=13
distribute
9-3y+5y=13
add -3y to 5y
9+2y=13
subtract 9 from both sides
2y=4
divide both sides by 2
y=2
substitute the value of y into an equation
x=3-2
subtract 3 to 2
x=1

Answer:
Step-by-step explanation:
Swap x and y, then solve for y.
The answer is 37!
