There are 52 cards in a standard deck, and 4 suits. There is one 9 per suit, so 4 cards, plus one 10 per suit, so 8 cards. 8 cards divided by 52 cards in a deck is 0.15384615 or 0.154.
The answer would be 272 because youre trying to find the decrease which is
340x.20 because you always move the percent over two decimals. you would get 68 after multiplying it then u would subtract that number by 340.

Step-by-step explanation:
Multilpy 
x (-5 + 5 x (3)
Calculate x (-5 - 15)
- x 20
= -5
Answer:
x = 5
Step-by-step explanation:
x² + (2x+2)² = (2x+3)²
x² + 4x² + 8x + 4 = 4x² + 12x + 9
x² - 4x - 5 = 0
(x - 5)(x + 1) = 0
x = -1 This can be discounted as the answer because you cannot have a negative length
answer: x = 5
