The correct answer is 18/30 which simplifies to 6/10. Hope this helps.
Answer:
The correct answer is

Explanation:
We are given the points:
(0, 4)
(1, 5)
(2, 6)
(3, 7)
We can see that for each unit that x-coordinate grows, the y-coordinate also grows one.
This means that the slope of the line is m = 1
The first point given, tell us the y-intercept: (0, 4)
The slope-intercept form of a line is:

Where m is the slope and b the y-intercept.
For the points given:
m = 1
b = 4
Thus:
Answer: There will be 22.694 grams of initial mass remains after 50 years.
Step-by-step explanation:
Since we have given that

We need to find the quantity of initial mass remains after 50 years.
So, t = 50 years,
We get that

Hence, there will be 22.694 grams of initial mass remains after 50 years.
Answer:
17
Step-by-step explanation:
Let the number be x
16 = 2x - 18
Add 18 to both sides
16+18 = 2x
2x = 34
Divide both sides by 2
x = 34/2
x = 17
