Three added to four times a number is equal to five less than six times the number

C: 4

Step-by-step explanation:

4x+3=6x-5

Add five to both sides

4x+8=6x

Subtract both sides by 4x

8=2x

Divide both sides by 2

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%
