Answer:

they are 16 and 4

Step-by-step explanation:

We can call the numbers x and y and we can write:

x - y = 12

x + y = 20

Adding these equations gives us 2x = 32 which means x = 16 and substituting this value into the first equation gives us y = 4.

Answer:

The numbers are 16 and 4

Step-by-step explanation:

Let the two numbers be x and y

x-y = 12

x+y = 20

Add the two equations together

x-y = 12

x+y = 20

-------------------

2x = 32

Divide by 2

2x/2 =32/2

x = 16

Now find y

x+y =20

16+y =20

Subtract 16

y = 20-16

y = 4

avanturin [10]

Answer:

Total number of cards in a standard deck of card=52

As deck of card contain 13 club +13 heart +13 spade+13 Diamond.

P(Diamond)=13/52  =1/4

If the card is not diamond then

P(not diamond)=39/52=3/4

Since after drawing card is not replaced

P ( second Diamond)=12/51

now if second card is not Diamond.then

P(non diamond)=39/51

Chances of your  winning i.e both cards are diamonds=1/4×12/51=1/17=0.0588..(approx)

chances of your friend winning=1/4×39/51=[1/4]×[13/17]=13/68=0.1911..(approx)

Your friend has got better chance to win because there are more chances that both the cards are not Diamonds.

seropon [69]
If Bobby claims Peter started with 21 cards, then we'll work this into our equation.

21 - 3 (that he lost) = 18
18 / 2 (the half he gave) = 9

So this means that he did have 21 cards to begin with. Please reply to this with a list of the answers that can/could be checked!

VLD [36.1K]
The ones where I had to dance. For me, I am not a big fan of dancing and we had to do the la cha cha as our warm ups everyday. It was so weird. I think I rather do 5 push-ups, 10 sit-ups and jumping jacks for a warm up instead. :V
