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
Answer:(updated)
2.4%
Step-by-step explanation:
$2.90-$2.83=$.07
.07/2.9=0.024137931(round to nearest ten<u>th</u>)=2.4%
or you can do 0.024137931*100 and get the same answer

Answer: y=15/x
For this problem you need to use trial and error.
For the first equation, 15-14 does equal 1, but 5-14 doesn’t equal 3. For the second equation, 15x15 doesn’t equal 1. For the third equation, 15+2 doesn’t equal 1. For the last equation, 15/15 is 1, 15/5 is 3, and so on. So, the last equation shows the relationship in the table.

Answer:
49849 x 83582 = 4166479118
96395 x 9384 = 904570680
8994 x 9692 = 87169848
4048 x 2048 = 8290304
