You have lost 5 cards.

In a normal deck of cards, there are 52 cards. If you take those 5 cards away, you have 47 cards.

If you are playing with 3 other people (meaning 4 people total), each person gets 11 cards (totaling 44 cards) and leaving 3 cards left over.

If you are playing with 2 other people (3 people total), each person gets 15 cards (totaling 45 cards) and leaving 2 cards left over.

If you are playing with 4 other people (5 people total), each person gets 9 cards (totaling 45 cards) and leaving 2 cards left over.

Thus meaning, you have lost 5 cards. I hope this helps!

Answer:

x + x+12 + 3(x+12) = 123

x = 15

Step-by-step explanation:

Jamil : x

Kiera : x+12

Luther : 3 ( x+12)

x + x+12 + 3(x+12) = 123

Distribute

x + x+12 + 3x+36 = 123

Combine like terms

5x+ 48 = 123

Subtract 48 from each side

5x+48-48 = 123-48

5x =75

Divide by 5

5x/5 = 75/5

x = 15

give brainliest please!

hope this helps :)

so these two angles add up to 180 degrees

7x -3 + 12x -7 = 180

7x+12x=180+7+3

19x=190

x=10

to check if this is true we can input 10 for x in each side.

7(10)-3 = 67

12(10)-7 = 113

113+67 = 180
