3 0

Answer:

$9x + \frac{7}{2} - (x - (x - \frac{2}{7} )) = 36 \\ 9x + \frac{7}{2} - x + x - \frac{2}{7} = 36 \\ 9x + \frac{7}{2} - \frac{2}{7} = 36 \\ 9x + \frac{49 - 4}{14} = 36 \\ 9x + \frac{45}{14} = 36 \\ 9x = 36 - \frac{45}{14} \\ 9x = \frac{504 - 45}{14} \\ 9x = \frac{459}{14} \\ x = \frac{459}{14 \times 9} = \frac{459}{126} \\ x = 3 . 64 \\ thank \: you$

33+34+35+36+...+104 what is the sum of the sequence?

Ray Of Light [21]

This is an arithmetic series, so we know, that:

Sum = (First term + Last term) * Number of terms /2

Here we have:

First term = 33
Last term = 104
Number of terms = 104 - 33 + 1 = 72

and

$S=(33+104)\cdot\dfrac{72}{2}=137\cdot36=\boxed{4932}$
