Whats the proportional relationship??? I will edit my question when I get further information
Answer:
x = 8, y = 3.
Step-by-step explanation:
11x − 20y = 28
3x + 4y = 36 multiply this equation by 5:
15x + 20y = 180
Add this new equation to the first one ( to eliminate the 20y):
26x = 208
x = 208/26 = <em> </em>8.
Substitute x = 8 into the second equation:
3(8) + 4y = 36
4y = 36 - 24 = 12
y = 3.

Answer:
x = 2
Step-by-step explanation:
2 to the second power is 4. 4 subtracted by 4 is zero.
The probability of the first item being good is 11/15.
Since we have taken 1 item out the remaining total is now 14, so the probability of getting a defective item is now 4/14.
Now you multiply the probabilities together to get (11/15)(2/7)=22/105
