A. 9 only bc only 9 can be equal to 9 if it was absolutely value then the answer would be 9 and -9
This equation basically says that a number plus 3/5 equals 2 so we can simply:
2 - 3/5 = x
Therefore x equals 1 & 2/5 or 1.4
2/5
Since 12 out of 30 marbles were black, you can assume that the percentage of black marbles in the bag is 40% (Ex: 12/30=.4) The probability that the marble you pick is black is equal to the percentage of black marbles in the bag. 40% is equal to 2/5.
Answer:
$41
Step-by-step explanation:
- One room rents for $68,
- Two rooms for $65 each,
- In general, the group rate per room is found by taking $3 off the base of $68 for each extra room.
So,
where 
is the rate per nth room rented.
This is an arithmetic sequence, so
In your case,
Hence
This means if a group rents 10 rooms, the charge per room is $41.
As we can observe from given information,
now, let's solve for y
