Look at the following sequence. 128, 320, 800, 2000, . . . If it is a geometric sequence, choose the common ratio. If it is not

OlgaM077 [116]

Answer:

It is a geometric sequence en the common ratio is: $r=\frac{5}{2}$ .

Step-by-step explanation:

1. By definition, a geometric sequence is a sequence in which you obtain a term by multiplying the previous one by a common ratio.

2. The common ratio is obtained by dividing a term by its preceding term.

3. Keeping this on mind, you have:

$\frac{320}{128}=\frac{5}{2}\\$

$\frac{800}{320}=\frac{5}{2}$

$\frac{2000}{800}=\frac{5}{2}$

4. As you can see, the common ratio is $\frac{5}{2}$

Solve for x 6 (8X minus 1) equals 9 (x + 2)

Oxana [17]

Answer:

x = $\frac{8}{13}$

Step-by-step explanation:

Given

6(8x - 1) = 9(x + 2) ← distribute parenthesis on both sides

48x - 6 = 9x + 18 ( subtract 9x from both sides )

39x - 6 = 18 ( add 6 to both sides )

39x = 24 ( divide both sides by 39 )

x = $\frac{24}{39}$ = $\frac{8}{13}$
