AlexFokin [52]

Correct question:

Every day Kim practice volleyball and clarinet each day she practices volleyball for 2.5 hours if after 8 days she practices both volleyball and the clarinet for a total of 36 hours how many hours per day did Kim practice clarinet.

Answer: 2 hours

Step-by-step explanation:

Everyday Kim practices volleyball and clarinet = v/ball + clarinet

Everyday volleyball practice = 2.5hours

That is clarinet(hours) + 2.5 hours of volleyball

After 8 day, total practice hours of both volleyball and clarinet equals 36 hours

The above information can be represented mathematically as thus:

Let h = hours per day of clarinet

8(h + 2.5) = 36

8h + 20 = 36

8h = 36 - 20

8h = 16

h = 16/8

h = 2

Solve the equation, and check the solutions 2(√x+3)=6.
zhannawk [14.2K]

Answer:

x = 0

Step-by-step explanation:

2(\sqrt{x}+3)=6

Expanding the left hand side we get

\Rightarrow 2\sqrt{x}+6=6

Taking 6 from left hand side to right hand side

\Rightarrow 2\sqrt{x}=6-6\\\Rightarrow 2\sqrt{x}=0

Dividing both sides by 2

\Rightarrow \sqrt{x}=\frac{0}{2}\\\Rightarrow \sqrt{x}=0\\\Rightarrow x=0

So, x = 0
