It would be 7/10 because since 10/10 is the Earth, and 3/10 is water, 10-3 is 7.

Answer:
85M + 4S <u><</u> 1000
Step-by-step explanation:
An inequality represents an expression that can have different values as long as the value is within the range given. In this case, the number of songs and movies that Caissa can download can not exceed 1000 MB. Since each move is 85 MB and each song is 4 MB, then any combination of these two files combined must not be larger than 1000 MB. Using the variable (M) for movies and (S) for songs, we can set up an expression 85M + 4S to represent the number of movies times 85 for each movie and the number of songs times 4 for each song. Since the total can be no greater than 1000, the expression would be less than or equal to (<u><)</u> 1000 MB.
The only equation that has 3 as the coefficient of x (a slope of 3) is ...
... d.) y = 3x+4
_____
Happily, it also goes through the given point.
... 5/2 = 3(-1/2) +4
... 5/2 = -3/2 + 8/2 . . . . true
The answer should be A. In order to solve these half-life problems, I encourage you to find an algebra calculator online, and plug in these numbers. The remaining grams goes in front, so 3.
The entire equation should look something like 3 = 15(1/2)^t/4.95
The 4.95 represents how long it takes before the sample halves, t is your answer, 1/2 represents the value halving every 4.95 hours, 15 is the initial sample size, and 3 is the end result that remains.
The overall answer should be about 11.5 hours, as per an algebra calculator.
Hope this helps solve any other similar problems
