Responder:

x = 15/7

Explicação passo a passo:

Dada a equação:

7 x + 4 = 19

Subtraia 4 de ambos os lados

7x + 4 - 4 = 19 - 4

7x = 15

Divida os dois lados por 7

7x / 7 = 15/7

x = 15/7

What is the value of the arithmetic series below?
xxTIMURxx [149]

Answer:

(A)-494

Step-by-step explanation:

Given the arithmetic series

S_{19}=\sum_{k=1}^{19}4-3k

The terms in the sequence are:

  • When k=1, 4-3k=4-3(1)=1
  • When k=2, 4-3k=4-3(2)=-2
  • When k=3, 4-3k=4-3(3)=-5

Therefore, the terms in the sequence are: 1, -2, -5, ...

First term, a =1

Common difference, d=-2-1=-3

The sum of an arithmetic series, S_n=\dfrac{n}{2}[2a+(n-1)d]

Therefore:

S_{19}=\dfrac{19}{2}[2(1)+(19-1)(-3)]\\=9.5[2+18*-3]\\=9.5[2-54]\\=9.5*-52\\=-494

The correct option is A.
