Distribute the 2 to the 3x and 7  then distribute the 5 to the x and 3 then combine your like terms such as 6x and 5x..which i think the answer is x-11 im not sure what are the answer choices?

The first term of a geometric sequence is –2 and the common ratio is -1/4. What are the next three terms of the sequence?
Gelneren [198K]
I agree with the answer being B because since it's a common ratio you could just multiply -1/4 with -2 and keep doing that with each new term

Find the ratio in simplest form.<br><br> 30:6<br><br> A. 1:5<br> B. 4:1<br> C. 5:1
nekit [7.7K]
ANSWER

The simplest form of the ratio
30:6
is

5:1


EXPLANATION

The ratio given to us is
30:6


We can divide each term in ratio by the same number.


To find the ratio in the simplest form we divide the terms in the ratio by their highest common factor, which is
6.


This implies that,

30:6 =  \frac{30}{6} : \frac{6}{6}


We simplify this to obtain,



30:6 = 5: 1


The correct answer is C.



Alternatively,


30:6 =   \frac{30}{6}


30:6 =   \frac{5}{1}


This implies that,


30:6 =   5:1

Find the sum of the first 20 terms of the arithmetic sequence 4, 10, 16, 22....
hammer [34]

n = 20

d = 6

a = 4

L = a + (n - 1)*d

L = 4 + (20 - 1)*6

L = 4 + 19*6

L = 118

Sum = (a + L)*n/2

Sum = (4 + 118) * 20/2

Sum = 122 * 10

Sum = 1220

If 5-3(2a+1)=-4a+10, what is the value of a+2​
AlekseyPX

Answer:

-2

<em>BRAINLIEST, PLEASE!</em>

Step-by-step explanation:

5 - 3(2a + 1) = -4a + 10

5 - 6a - 3 = -4a + 10

2 - 6a = -4a + 10

-2a = 8

a = -4

-4 + 2 = -2
