Answer: 2:45
Step-by-step explanation: You add 30 minutes to 1:00, which is 1:30. Next, add 45 to 1:30, which is 2:15. Then, add 30 to 2:15 and you get 2:45!
Answer:
Step-by-step explanation:
First let's multiply both sides by 2 to remove the 
fraction:
Next, let's divide both sides by 
:
Finally, let's subtract 
from both sides:
The asnwer is 3u-4
just divide like terms
Answer:
The difference between combinations and permutations is that in permutations, the order matters, while it doesn't with combinations. For example, if you are given 5 numbers (1,2,3,4,5) and you have to determine how many 3 digit numbers you can make, that is a permutation question because 123, 231, 321, etc. are all different numbers. If, for example, we have to find how many ways three people can be chosen out of a group of 5, that is a combination question and you must use the combination formula as the order of the three people does not matter. Other than the order, combinations and permutations are the same
5.1=s. Use the distributive property and add like terms
