Answer:
1. 0.83 = 83%
2. 6.1% = 0.061
Step-by-step explanation:
The answer in number one is because when you're trying to find a percentage from a decimal, all you have to do is multiply your decimal by 100, this is because a percentage is always out of 100.
The answer in number two is exactly the opposite, all you have to do is divide by 100 if you are trying to find your decimal from a percentage.
Answer:
The root symbol (√ ) is used to represent the square root of any number.
Answer:
-3/5 + 1/3 = ___
-9/15+5/3 equals -4/15
You cannot simplify this so the answer is -4/15.
Let the number of one-bedroom apartments be x, and the number of two-bedroom apartments be y.
If there are a total of 60, then x + y = 60.
If there are twice as many 1-bedroom apartments as there are 2-bedroom ones, then x = 2y.
Substitute x = 2y into the first equation to get 2y + y = 60, or y = 20.
Substitute y = 20 into the second equation to get x = 40.
Therefore, there are 40 one-bedroom apartments and 20 two-bedroom apartments in the building.
