Answer:
y=4/9
Step-by-step explanation:
Substitute 2y into the x
2(2y)+5y=4
4y+5y=4
9y=4
y=4/9
16 x 3/8 so 16/1 x 3/8 = 48/8. 48 divided by 8 is 6. So 6 inches.

Answer:
Probability is: 
Step-by-step explanation:
From a deck of 52 cards there are 26 black cards. (Spades and Clubs).
Also, there are 26 red cards. (Hearts and Diamonds).
First, we determine the probability of drawing a black card.
P(drawing a black card) =

Now, since we don't replace the drawn card, there are only 51 cards.
But the number of red cards is still 26,
∴ P(drawing a red card) =

Now, the probability of both black and red card =

Hence, the answer.
2x - 2y = -4
-3x -3y = 0
