Answer:

x = -14

Step-by-step explanation:

-3(x + 9) = 15

Divide each side by -3.

-3(x + 9)/-3 = 15/-3
x + 9 = -5

Subtract 9 from each side.

x + 9 - 9 = -5 - 9
x = -14

Answer:

x = -14

Step-by-step explanation:

-3(x + 9) = 15

-3 × x + -3 × 9 = 15
-3x + (-27) = 15
+27 on both sides
-3x = 42
$\frac{ - 3x}{ - 3} = \frac{42}{ - 3}$
x = -14

Write the next three terms of the arithmetic sequence.

JulijaS [17]

The next three terms are: 1/6 , 0 and -1/6

Step-by-step explanation:

Given sequence is:

$\frac{5}{6} , \frac{2}{3} ,\frac{1}{2}, \frac{1}{3} ...$

First of all, we have to find the common difference

$here\\a_1 = \frac{5}{6}\\a_2 = \frac{2}{3}\\a_3 = \frac{1}{2}\\a_4 = \frac{1}{3}\\d = a_2-a_1 = \frac{2}{3} -\frac{5}{6} = \frac{4-5}{6} = -\frac{1}{6}\\d = a_3 - a_2 = \frac{1}{2} - \frac{2}{3} = \frac{3-4}{6} = =\frac{1}{6}$

The common difference is -1/6

We can simply add -1/6 to the previous term to find the next terms so,

Adding -1/6 to 1/3

$\frac{1}{3} - \frac{1}{6} = \frac{2-1}{6} = \frac{1}{6}\\\frac{1}{6} - \frac{1}{6} = 0\\0-\frac{1}{6} = -\frac{1}{6}$

Hence,

The next three terms are: 1/6 , 0 and -1/6
