Answer:
2x+y=7
5x-3y=1
we do reduction.
3(2x+y=7)............6x+3y=21
5x-3y=1............... 5x-3y=1
11x=22.......x=22/11.............. x=2
if x=2
2x+y=7
2(2)+y=7
4 +y=7
y=7-4
y=3
solution:
x=2 y=3
Ok so
1/4 of total eaten
3/4 left
3/5 of 3/4 eaten
9/20 left
18=9/20 of whole
multiply both sides by 20
360=9 of whole
divide both sides by 9
40=whole
40 total originlly
Answer:
$2.56
Step-by-step explanation:
P(7 or 11) = 8/36 = 2/9
P(winning 20-2 = 18) = 2/9
P(2 or 12) = 2/36 = 1/18
P(winning 2-2 = 0) = 1/18
P(others) = 26/36 = 13/18
P(winning 0-2 = -2) = 13/18
Expected win
= 18(2/9) + 0(1/18) - 2(13/18)
= $23/9 or $2.56
