Let "a number" be represented with the variable x.
Solve the expression by breaking it apart:
"...the sum of four and a number": (x + 4)
"twice of...": 2(
"Twice of the sum of four and a number": 2(x + 4)
2(x + 4) is your answer.

Answer:
8:27
Step-by-step explanation:
1 way to do it is...
The volume of a sphere is 4/3*pi*r^3. Plugging in 2 and 3 in for the radii you get the volumes are about 33.51 and 113.1, which is an 8:27 ratio.
Another way to do it is...
The ratio of the radii is 2:3 and a radius is 1-dimensional. The volume, however is 3-dimensional. To get from 1-D to 3-D, you have to cube the numbers. 2^3 is 8 and 3^3 is 27, so the ration is 8:27.
Alright, lets get started.
We are asked, approximately how many meters are equal to 11.4 feet.
We have given that,
3.3 feet = 1 meter
So, 1 feet = 
meter
So, 11.4 feet = 
meter
11.4 feet = 
meter
11.4 feet = 3.45 meters : Answer
Hope it will help :)
In order to find the answer to this question, you would need to find the Greatest Common Factor of 16 and 12 which would be 4 because 4 is the greatest amount that you can divide both 12 and 16 by. So the soonest both ships will leave together again will be in 4 days.
