9 divided by 72 = 0.125
0.125 is the weight of one book
0.125 times 80 = 10kg.
So 80 books weight 10kg.
72 divided by 9 = 8 books make up 1 kg.
8 times 6 =48

The complete exercise is: "Which arrangement shows
, 3.7,
, and 3.89 in order from least to greatest?"</h3><h3>
</h3>
Convert from mixed numbers to decimal numbers.
The steps to do this, are the following:
1. You must divide the numerator of the fraction by the denominator.
2. Then you must add the quotient obtained to the whole number part.
Applying this procedure, you get that:


Now that you have all the numbers in decimal form, you can order from least to greatest:

Therefore, you can conclude that the correct arrangement is:

Given:
A line passes through the points (2,-1) and (1,-5).
To find:
The equation of the line.
Solution:
If a line passes through the two points, then the equation of the line is

The line passes through the points (2,-1) and (1,-5). So, the equation of the line is




Using distributive property, we get


Subtract 1 from both sides.


Therefore, the correct option is B.
