Step-by-step explanation:
• no solution:
3x+9+4x+x = 8x + 9
• one solution:
3x+9+4x+x = 7x + 11
• infinitely many solutions:
3x+9+4x+x = 8x + 11
Find a common multiplier then divide ex. 21/27 = 7/9
Answer:
That is correct.
Step-by-step explanation:
2 times 10=20
4 times 1=4
5 times 0.1=0.5
8 times 0.01=0.08
20+4+0.5+0.08=24.58
That is correct.
The probability of getting a <em>country CD</em> out of all the CDs is the number of <em>country CDs</em> divided by the <em>total number of CDs</em> in Dante's Collection.
The <em>total number of CDs</em> in Dante's collection is
.
