Ratio is a comparison of two values or two quantities.
Fraction is a another form of ratio.
The first term and the second term in the ratios are important.
It should not be changed.
The first quantity value is in first term and the second quantity value is in second term of the ratio.
Ratio and fractions are same.
Example:
The ratio of male to female in the school is 5 : 6.
5 represents male students and 6 represents female students.
The fraction form of the above ratio is 
By applying the segment addition postulate, the <u>value of v = 7</u>
- According to the Segment Addition Postulate, it holds that if point C is between points D and E, therefore:
DC + CE = DE

- Therefore, by substitution, we will have the following equation:

- Open the bracket and solve for the value of v.



v = 10
Therefore, using the segment addition postulate, the <u>value of v = 10</u>

you can apply the property mentioned before. Then:

(It is the equivalent expression)
B. Add the exponents:

(It is not the equivalent expression)
C. For
you can apply the property mentioned before. Then:

(It is not the equivalent expression)
D. We know that
and we maje the addition indicated in this option, we get:

Answer:
8by + 2ax - 4bx - 4ay
Step-by-step explanation:
I assume you mean expand so:
(a - 2b)(3x - 5y) + (2b - a)(x - y)
3ax - 5ay - 6bx + 10by + 2bx - 2by - ax + ay
Now collect like terms:
2ax - 4ay - 4bx + 8by
This is your answer but in a better order:
8by + 2ax - 4bx - 4ay
Answer:
30
