Answer:
Option A is correct.
The equation = .
Explanation:
Sum of the terms of an arithmetic series is given by
, ......[1]
where n is the number of terms, is the first term and is the last term.
Given the formula for nth term in the arithmetic sequence is,
for n =1
for n =9
Then, put these values in equation [1] for n =9;
or
Therefore, the equation is;
The answer to this question is 51,282.
Answer:
x = -4
Step-by-step explanation:
2x + 9 (x-1) = 8(2x + 2) -5
2x + 9x - 9 = 16x + 16 - 5
11x - 9 = 16x +11
-9 = 5x +11
-20= 5x
x= -4
1 1/2:2 1/3:1 1/6
To simplify these numbers you need to subtract the denominator from the numerator and the number you get you put that on top of the numerator then you divide the denominator from the numerator to get a whole number.
