m = 16
8 6
Cross multiply:
m * 6 = 8 * 16
Simplifying
m * 6 = 8 * 16
Reorder the terms for easier multiplication:
6m = 8 * 16
Multiply 8 * 16
6m = 128
Solving
6m = 128
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Divide each side by '6'.
m = 21.33333333
Simplifying
m = 21.33333333
X - (-2) = 21 <== ur equation
x + 2 = 21
x = 21 - 2
x = 19

Answer:
x = 4
Step-by-step explanation:
We can find the answer to this by solving the equation:
3x - 4 = 8
3x - 4 + 4 = 8 + 4
3x = 12
x = 4
Answer:
The sum of the first 650 terms of the given arithmetic sequence is 2,322,775
Step-by-step explanation:
The first term here is 4
while the nth term would be ai = a(i-1) + 11
Kindly note that i and 1 are subscript of a
Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula
Sn = n/2[2a + (n-1)d)
Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.
Plugging these values, we have
Sn = (650/2) (2(4) + (650-1)11)
Sn = 325(8 + 7,139)
Sn = 325(7,147)
Sn = 2,322,775
