Part 1) $13\ diamonds$

Part 2) $y=3\ chandeliers$

Part 3) $x=52\ diamonds$

Part 4) $x=130\ diamonds$

Part 5) $y=40\ chandeliers$

The complete table in the attached figure N 2

Step-by-step explanation:

see the attached figure N 1 to better understand the problem

Let

x -----> the number of diamonds

y ----> the number of chandeliers

we know that

The ratio between the number of diamonds to the number of chandeliers is equal to

$\frac{x}{y}=\frac{39}{3}$ ----> equation A

Complete the table

Part 1) Find the number of diamonds if the number of chandeliers is equal to 1

For y=1

substitute in the equation A and solve for x

$\frac{x}{y}=\frac{39}{3}$

$\frac{x}{1}=\frac{39}{3}$

$x=13\ diamonds$

Part 2) Find the number of chandeliers if the number of diamonds is equal to 39

For x=39

substitute in the equation A and solve for x

$\frac{x}{y}=\frac{39}{3}$

$\frac{39}{y}=\frac{39}{3}$

$y=3\ chandeliers$

Part 3) Find the number of diamonds if the number of chandeliers is equal to 4

For y=4

substitute in the equation A and solve for x

$\frac{x}{y}=\frac{39}{3}$

$\frac{x}{4}=\frac{39}{3}$

$x=52\ diamonds$

Part 4) Find the number of diamonds if the number of chandeliers is equal to 10

For y=10

substitute in the equation A and solve for x

$\frac{x}{y}=\frac{39}{3}$

$\frac{x}{10}=\frac{39}{3}$

$x=130\ diamonds$

Part 5) Find the number of chandeliers if the number of diamonds is equal to 520

For x=520

substitute in the equation A and solve for x

$\frac{x}{y}=\frac{39}{3}$

$\frac{520}{y}=\frac{39}{3}$

$y=40\ chandeliers$

the dude above me is super complicated so let me say this

Step-by-step explanation:

39diamonds/3chandelier. 39/3 can be simplified to 13/1, so 13 diamonds for every one chandelier. +13 for every chandelier so the graph will be:

1. 13/1

2. 26/2

3. 39/3

4. 52/4

5. 65/5

6. 78/6

7. 91/7

8. 104/8

9. 117/9

10. 130/10

This is all I am doing. but do 13+ on Diamonds for next one and 1+ for the chandelier.

Or you can multiply the 13 by the number of chandeliers there are. So 13 diamonds for one chandelier will be multiplied by 40 to get the number of diamonds needed for 40 chandeliers. So 520 needed for 40 chandeliers.

Mark brainliest please :)

i'm pretty sure it's c. nvm

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
