Answer & Step-by-step explanation:

8.5x-6.1=-7.1

Add 6.1 to both sides:

8.5x-6.1+6.1=-7.1+6.1\\\\8.5x=-1

Isolate the variable x. Divide both sides by 8.5:

\frac{8.5x}{8.5} =\frac{-1}{8.5}\\\\ x=-\frac{1}{8.5}

Round to the nearest tenth. Simplify division:

-\frac{1}{8.5}=-0.11764705...=-0.1

So, x≈-0.1

:Done

There are 16 players in my poker group that meets the first Tuesday of every month. Ten of the players are male and six are fema
rodikova [14]

Answer:   Hello mate!

in your group, there are 16 players, 10 males, and 6 females.

in this case, 5 males already arrived (then there are 5 other males left)

and 4 females already arrived (then there are other 2 females left)

then there are a total of 7 players left, where 2 are female and 5 are males.

you want to know the probability that the next person through the door will be a male.

this is the number of male players left, divided by the number of players left: 5/7 = 0.71

then the probability that the next person through the door will be a male is 0.71.
