The common ratio of the geometric sequence -14,-84,-504
Answers
A common ratio is basically a ratio of next sequence and the sequence you want
To find a common ratio of geometric sequence, we usually define 'r' as common ratio.
[tex] \displaystyle \large \tt{r = \frac{next \: \: sequence}{the \: \: sequence \: \: you \: \: want} }[/tex]
For example, I want to focus on -14 and the next sequence would be -84.
Hence,
[tex] \displaystyle \large{r = \frac{ - 84}{ - 14} }[/tex]
Thus, r is 6 because both numerator and denominator are negative. negative divides negative = positive.
Or you want to choose -84, then the next sequence would be -504.
[tex] \displaystyle \large{r = \frac{ - 504}{ - 84} }[/tex]
Then r would still be 6. Since both ways have r as 6 and this proves that the sequence is geometric.
Hence, the common ratio is 6.

Answers
Answer: 13y - 55
Step-by-step explanation:
Given
7 (3y - 5) - 2 (10 + 4y)
Expand parentheses and apply the distributive property
=7 · 3y - 7 · 5 - 2 · 10 - 2 · 4y
=21 y - 35 - 20 - 8y
Move like terms together
=21y - 8y - 35 - 20
Combine like terms
=13y - 55

You are taking hang-gliding lessons. The cost of the first lesson is one and a half times the cost of each additional lesson. You spend $260 for six lessons.
Answers
First thing to do is to figure out how many additional lessons are in that, which are 5.
Then you can make a 1 variable equation with the information you have. I’m using x as my variable.
260= 3/2x + 5x
Combine like terms.
260 = 13/2x
Divide both sides by 13/2 (treat it as a fraction, and if your calculator cannot make fractions, then decimal might help for this. 13/2=6.5)

[tex]x = -\frac{17}{6} = -2\frac{5}{6}[/tex]
Step-by-step explanation:
When I went through the phase of solving these problems they stumped me SO BAD,... they want you to solve for x,...
Here's your problem:
[tex]-\frac{3}{4} =\frac{3x}{4} +\frac{11}{8}[/tex]
Multiply both sides of the equation by 8, the least common multiple of 4,8. (in doing this you get all the fractions to whole numbers (they are easier to work with))
−6=2×3x+11
Multiply 2 and 3 to get 6
−6=6x+11
Swap sides so that all variable terms are on the left hand side.
6x+11=−6
Subtract 11 from both sides.
6x=−6−11
Subtract 11 from −6 to get −17.
6x=−17
Divide both sides by 6.
x= [tex]\frac{-17}{6}[/tex]
