Answer: 2 11/24
Step-by-step explanation:
How many hours does the plane save?
Time taken for the train = 5 1/8
Time taken for the plane = 2 2/3
The number of hours saved will then be:
= 5 1/8 - 2 2/3
Let the lowest common multiple be 24
= 5 3/24 - 2 16/24
= 2 11/24
The number of hours saved by the plane will be 2 11/24
Answer:
The greater number is 4π^2.
Step-by-step explanation:
1) 4π^2 = 39.4784176044
2) 
= 31.304951685
4π^2 is greater.
Answer: No Solution
Step-by-step explanation:
y=2x+1 and 2x-y=3
Substitute y=2x+1 into 2x-y=3
So you will have: 2x-2x+1=3
Then,
2x-2x=0
0+1=3
1=3
1 doesn't equal 3 so there is no solution.
Answer:
105 11/12
Step-by-step explanation:
With mixed numbers you can also write them as functions so 5 11/12 could also be written as 5+11/12.
Once you have rewritten the mixed number it's simply a matter of addition: 100+5+11/12
