Answer:

4. x = 11

5. x = -13

Step-by-step explanation:

4. 3x + 7 = 5x - 15

-7 -7

3x = 5x - 22

-5x -5x

-2x = -22

-2x/-2 = -22/-2

x = 11

5. 3(2x - 5) = 9x + 24

6x - 15 = 9x + 24

+15 +15

6x = 9x + 39

-9x -9x

-3x = 39

-3x/-3 = 39/-3

x = -13

Hope this helps, have a great day:)

Nadya [2.5K]

Answer:

1.5

Step-by-step explanation:

As the common difference is not same for all terms, the given sequence is a geometric sequence

the standard formula for a geometric sequence is:

$a_n=a_1r^{n-1}$

The formula to calculate common ratio is:

$r = \frac{a_n}{a_{n-1}}$

Dividing the term by previous term

So,

r = 12/8 = 18/12 = 27/18 = 1.5

The value for common ratio will be:

1.5 ..

6-1/3x=-1 How do I do this

I am Lyosha [343]

Im gonna assume you mean 6 - (1/3)x = -1. Your notation is not super clear. If so, solution is as follows:

6 - (1/3)x = -1 [subtract 6 from both sides]
-(1/3)x = -7 [multiply both sides by -3]
x = 21
