Find use the distributive property and bring down the ending result (21)
-3x-6=21

Next, add 6 on both sides and you should get:
-3x = 27

The last step is, you divide -3 from 27 and you end up with 9. So, the total answer is x = 9

Describe the relationship between the terms in each arithmetic sequence. Then
shtirl [24]

Answer:

(a) The sum of the previous term and 9

(b) 36, 45, 54

Step-by-step explanation:

Given

Sequence: Arithmetic Progression

0,9,18,27

Solving (a): Describe the relationship in each term

First, we calculate the common difference (d)

In arithmetic progression:

d = T_n - T_{n-1}

Take n as 2

d = T_2 - T_{2-1}

d = T_2 - T_{1}

Where

T_2 = 9\ and\ T_1 = 0

d =9-0

d =9

<em>The relationship is: The sum of the previous term and 9</em>

Solving (b): The next three terms

As said in (a) each term is derived from a sum of 9 and the previous term

So, we have:

Next\ Term = 27 + 9 = 36

Next = 36 + 9 = 45

Next = 45 + 9 = 54

Hence, the next three terms are: 36, 45 and 54

3(2c-8) - 10c &gt; 0 can some one explain how to solve this ?​
Jet001 [13]

Answer:

c < - 6

Step-by-step explanation:

Given

3(2c - 8) - 10c > 0 ← distribute and simplify left side

6c - 24 - 10c > 0

- 4c - 24 > 0 ( add 24 to both sides )

- 4c > 24

Divide both sides by - 4, reversing the inequality symbol as a consequence of dividing by a negative quantity.

c < - 6
