Let c and d be the number of cds and dvds respectively.
c+d=12
c=12-d
The we are told that:
2c+3d=31, using c found above in this equation gives you:
2(12-d)+3d=31
24-2d+3d=31
24+d=31
d=7
So Phillip bought 7 dvds.
check...
3*7+2(12-7)=31
21+2(5)=31
21+10=31
31=31
It would be 32cm because the diameter corresponding
To find out the answer we divide 0.09 by 10:

÷10=0.009.
Therefore, 0.09 is 10 times as much as 0.009.
