0.1x=0.2(x+2)\ \ \ |mltiply\ both\ sides\ by\ 10\\\\10\cdot0.1x=10\cdot0.2(x+2)\\\\1x=2(x+2)\ \ \ |use\ distributive\ property:a(b+c)=ab+ac\\\\x=(2)(x)+(2)(2)\\\\x=2x+4\ \ \ \ |subtract\ 2x\ from\ both\ sides\\\\x-2x=2x-2x+4\\\\-x=4\ \ \ \ |change\ signs\\\huge\boxed{x=-4}

check\\subtitute\ the\ value\ of\ x\ to\ the\ equation:\\L_s=0.1\cdot(-4)=-0.4\\R_s=0.2(-4+2)=0.2(-2)=-0.4\\\\L_s=R_s\ \ \ |correct\ :)

0.1x = 0.2(x + 2)

First, divide both sides by 0.1 / Your problem should look like: x = 2(x + 2)
Second, expand. / Your problem should look like: x = 2x + 4
Third, subtract 2x from both sides. / Your problem should look like: x - 2x = 4
Fourth, simplify x - 2x to -x. / Your problem should look like: -x = 4
Fifth, multiply both sides by -1. / Your problem should look like: x = -4

Answer: x = -4

Consider the first 2 terms of the sequence -6, 18,...
____ [38]

Answer:

arithmetic sequence: 24, 42, 66, 90, 114; y = 24x - 30

geometric sequence: -54, 162, -486, 1458, -4374; y = -6(-3)^(x - 1)

Step-by-step explanation:

Arithmetic sequence:

-6, 18, ...

18 - (-6) = 24

18 + 24 = 42

42 + 24 = 66

66 + 24 = 90

90 + 24 = 114

y = -6 + 24(x - 1)

y = -6 + 24x - 24

y = 24x - 30

Geometric sequence:

-6, 18, ...

18/(-6) = -3

18 * (-3) = -54

-54 * (-3) = 162

162 * (-3) = -486

-486 * (-3) = 1458

1458 * (-3) = -4374

y = -6(-3)^(x - 1)
