Answer:
Option 4 - 
Step-by-step explanation:
To find : Which set of rational numbers is arranged from least to greatest?
Solution :
The set of rational numbers are

Writing all number in one form,


Now, -1.4<-0.5<0.2<3
From least to greatest the set of natural numbers are

So, 
Therefore, option 4 is correct.
Answer:
I think the answer is 8
Step-by-step explanation:
Answer: option c
Step-by-step explanation:
Find the x-intercept and y-intercept of each line.
To find the x-intercept, substitute
into the equation and solve for "x".
To find the y-intercept, substitute
into the equation and solve for "y".
- For the first equation:
x-intercept

y-intercept

Graph a line that passes through the points (7.25, 0) and (0, 9.66)
- For the second equation:
x-intercept

y-intercept

Graph a line that passes through the points (0.5, 0) and (0, -0.33)
Observe the graph attached. You can see that point of intersection of the lines is (5,3); then this is the solution of the system. Therefore:

Simply substitute the point into the given equation; as there is one variable, you only need one point and so one is given. When done so, you shall get b=4
