-6h + 4 = 8 solve for h

h = -2/3

Step-by-step explanation: -6h + 4 = 8                                                  

                                                     -4    -4                                              

                                            -6h/-6 = 4/-6

                                             h = -2/3

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%

good luck on your studies! : )
