Answer:
(x, y) = (5, 1)
Step-by-step explanation:
To <em>eliminate</em> x, you can double the second equation and subtract the first.
... 2(x +4y) -(2x -3y) = 2(9) -(7)
...11y = 11 . . . . . simplify
... y = 1 . . . . . . divide by 11
Using the second equation to find x, we have ...
... x + 4·1 = 9
... x = 5 . . . . . subtract 4
_____
<u>Check</u>
2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation
(Since we used the second equation to find x, we know it will check.)
B is 2 out of 12
c is if you were talking probability then you would have put down one out of 6 because there is one 3 out of 6 sides but i believe i would expect to see two times 34 because it is two time the dice and it gives you the capability to earn three twice as much so you should see it at least 68 times

Answer: 6.5%
Step-by-step explanation:
$5.86 -$5.50
=$0.36
We then divide $0.36 by 5.50 =0.065
Multiply by 100 to convert decimal to percentage= 0.065×100
=6.5%
