Answer:

Step-by-step explanation:
8X +6Y=4
Y=-3X+9
Substitute the second equation into the first. Every place you see y put -3x+9)
8x +6(-3x+9)=4
Distribute
8x-18x +54 = 4
Combine like terms
-10x +54 = 5
Subtract 54 from each side
-10x +54-54=4-54
-10x = -50
Divide by -10
-10x/-10 = -50/-10
x= 5
Now we need to find y
y = -3x+9
y = -3(5) +9
y = -15+9
y= 6

The number of individual people represented in the person data set as indicated by the person_if is; 9 individuals.
The number of contacts made with people from family 3 as in the task content is; 3 contacts, namely, G, H and I.
<h3>How many individual people are represented in the person dataset?</h3>
As evident in the task content, we are expected to access the table and evaluate the data representation in order to draw inferences from observation.
The person_id column assigns an alphabet to each individual.
Hence, the total number of individuals represented in the person data set is; 9 individuals.
Also, since only persons G, H and I are evaluated in family 3, it follows that the total number of individuals checked in family 3 is; 3.

Answer:
Depth of Martens aquarium water = 14 cm.
Step-by-step explanation:
Given:
An aquarium,which is a right rectangular prism.
Length of the aquarium, 
= 18.5 cm
Width of the aquarium, 
= 15 cm
Volume of the aquarium, 
= 3885 cm cubes
We have to find the depth of the aquarium.
Let the depth be 
cm.
Note:
Volume of the rectangular prism,V=lbh.
⇒ = 
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
cm
So,
The depth of the aquarium water is 14 cm.
