Answer:
Step-by-step explanation:
When adding or subtracting rational expressions, it is easiest to find a common denominator.
Ex.
The common denominator would be 
We need to make both fractions have that denominator
Answer:
33%
Step-by-step explanation:
sorry my bad i did percentage increase.
Let's go through each answer choice one at a time.
--------------------------------------------------
Choice A
3/4 < 5/7
3*7 < 4*5 ... cross multiply
21 < 20
The last inequality is false, so the original inequality is false
Choice A is false
--------------------------------------------------
Choice B
2/3 > 5/6
2*6 > 3*5 ... cross multiply
12 > 15
The last inequality is false, so the original inequality is false
Choice B is false
--------------------------------------------------
Choice C
5/8 > 6/10
5*10 > 8*6 ... cross multiply
50 > 48
The last inequality is true, so the original inequality is true
Choice C is true
--------------------------------------------------
Choice D
4/5 < 2/9
4*9 < 5*2 ... cross multiply
36 < 10
The last inequality is false, so the original inequality is false
Choice D is false
--------------------------------------------------
In summary, we have
A. False
B. False
C. True
D. False
So the final answer is choice C
Given:
First 10 term of a geometric series are:
To find:
The expression that represents the sum of the series.
Solution:
The first term of the given geometric series is:
The common ratio of the given geometric series is:
The sum of first n terms of a geometric sequence is:
Where r is the common ratio.
Putting 
in the above formula, we get
Therefore, the correct option is C, i.e., 
.
9514 1404 393
Answer:
B) f(1)=7, f(n+1)= f(n)-3; for n >= 1
Step-by-step explanation:
The first term of the sequence is 7 and the next (4) is found by adding -3 to that: 4 = 7-3. This is described in answer choice B.
