Answer:
a. x/y = 2 b) y/x +y =1/3 c) x-y/y= 1 d) y/x = 1/2
Step-by-step explanation:
Solve for
a) x/y
as we know x +y/y = 3
x+y= 3y
x= 3y-y
x= y(3-1)
x/y= 3-1
x/y = 2
b) y/x+y
as we know x +y/y = 3
x+y = 3y
1= 3y/x+y
1/3 = y/x+y
So y/x +y =1/3
C) x-y /y
as we know x +y/y = 3
x +y = 3y
subtracting 2y from both sides
x +y -2y = 3y- 2y
x-y = y
dividing both sides by y
x-y/y = y/y
x-y/y= 1
d) y/x
as we know x +y/y = 3
x +y = 3y
x= 3y- y
x= 2y
dividing both sides by x
x/x = 2y/2x
1 = 2 x (y/x)
1 / 2 = y/x
Or y/x = 1/2
Best of luck.

If it starts at 5 degrees celsius and raises to 15 degrees celsius in 3 minutes it increases by about 3 1/3 every minute.
times that by 5 and you get 16 2/3. times that by 10 and you get 33 1/3
Answer:
<h2>The answer is 0.1493.</h2>
Step-by-step explanation:
In a standard deck there are 52 cards in total and there are 4 aces.
Two cards can be drawn from the 52 cards in 
ways.
There are (52 - 4) = 48 cards rather than the aces.
From these 48 cards 2 cards can be drawn in 
ways.
The probability of choosing 2 cards without aces is 
.
The probability of getting at least one of the cards will be an ace is 
.
Answer:
18+45x
Step-by-step explanation:
Answer:
From given, we have,
Paul says he is 16 inches shorter than 1 1/2 times Theresa's height.
Steve says he's 6 inches shorter than 1 1/3 times Theresa's height.
Let the height of Theresa be "x" inches.
So, we get,
For Paul, 1 1/2 x - 16 = T
⇒ 3/2 x - 16 = T ......(1)
For Steve, 1 1/3 x - 6 = T
⇒ 4/3 x - 6 = T .........(2)
equating equations (1) and (2), we get,
3/2 x - 16 = 4/3 x - 6
6 - 16 = 4/3 x - 3/2 x
-10 = (8 - 9)/6 x
-60 = -x
x = 60 inches.
Therefore, Theresa is 60 inches tall.
