Answer: A. inverse variation; xy = 20
ANSWER
Step-by-step explanation: Brainly
B) xy=20
Inverse because it is of the form y=k/x, intuitively you can see that as x increases y decreases, hence "inverse variation".

Answer:
Option B is correct
Inverse variation , xy = 20
Step-by-step explanation:
Inverse variation states:
If
then the equation is in the form of:
or
xy = k ....[1]
As per the statement:
Given the data:
x : 2 4 8 12
y : 10 5 5/2 5/3
Let any value of x and y to find k:
x = 4 and y = 5
Substitute in [1] we have;
⇒20 = k
or
k = 20
then we get;
xy = 20
Check:
Substitute x = 12 and y = 5/3
⇒ true.
Therefore, the the data in the table represent a inverse variation and an equation to model the data in the table is, xy = 20
<u>Answer:</u>
7th Place
<u>Step-by-step explanation:</u>
Seeing as how the number of runners in front of Paula is 
the number of runners behind her,
Assign the number of people behind Paula to a variable:
# of people behind Paula = b, which means
# of people ahead of Paula = b
Use the variable to make an equation:
b (people behind Paula) + b (people ahead of Paula) + 1 (Paula) = 25
b + b + 1 = 25
Solve for b:
b + b + 1 = 25
b + b = 24
b = 24
b = 18
If there are 18 people behind Paula, there are * 18 people in front of her, which is 6; This puts Paula in 7th place.
Answer:
2.94
Step-by-step explanation:
SA
Area of one plane moultyply by number of planes
0.7*0.7*6
=2.94
Don’t trip just use the distributive property. -5(3x-2)= -50 which would end up being -15x -7 = -50; then add 7 to both -7 which then they will cancel out and add 7 to -50 which equal -43 so x = -43
