9(x+3)=3(3x+6)+9 how many solutions?

Slav-nsk [51]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$9(x +3) = 3(3x + 6) + 9$

$9x + 27 = 9x + 18 + 9$

$9x + 27 = 9x + 27$

The two sides of this equation are exactly the same, so the above equation holds for any value of x , thus we have infinite solution for it.

I think the answer is A Correct?

xeze [42]

You can see that there are 6 rock CDs, over a total of

$6+10+4+8+12 = 40$

So, the ratio of rock CDs over the total number of CDs is

$\dfrac{6}{40} = 0.15$

Which is 15%.

So, yes, the answer is A
