x=2.52

Step-by-step explanation:

30.16=17.56+5x

Subtract 17.56 from both sides

12.6=5x

17.56 cancels on the right side

Divide 5 to both sides

5 cancels on right side  

12.6/5=2.52

x=2.52

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

ok
