2х + 6 = 7x - 14
What’s the answer?

Step-by-step explanation:

=> 2x+6 = 7x-14

Subtracting 2x to both sides

=> 6 =7x-2x-14

=> 6 = 5x-14

Adding 14 to both sides

=> 6+14 = 5x

=> 20 = 5x

=> 5x = 20

Dividing both sides by 5

=> x = 20/5

=> x = 4

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%
