Answer:
x = -9
Step-by-step explanation:
let the number = x
So x ÷ -3 = x + 12
Mulitply both sides by -3: x = -3x -36
Add 3x to both sides: 4x = -36
Divide both sides by 4: x = -9
Answer is J not blue because the complement (opposite of being it) is 3/4. Blue is 1/4, so not being blue is 3/4.
Hope this helps :D

Answer:
The answer to your question is below
Step-by-step explanation:
Data
Equation 25x² + 64y² = 1600
Process
1.- Divide all the equation by 1600
25x²/1600 + 64y²/ 1600 = 1600/1600
-Simplify
x²/64 + y²/ 25 = 1
2.- Equation of a horizontal ellipse
3.- Find a, b and c
a² = 64 a = 8
b² = 25 b = 5
-Calculate c with the Pythagorean theorem
a² = b² + c²
-Solve for c
c² = a² - b²
-Substitution
c² = 8² - 5²
-Simplification
c² = 64 - 25
c² = 39
-Result
c = √13
4.- Find the center
C = (0, 0)
5.- Find the vertices
V1 = (-8, 0) V2 = (8, 0)
6.- Find the foci
F1 = (-√13, 0) F2 = (√13, 0)
The direction of the difference between the 2 measurements.
<h3>What is nominal and ordinal scale with example?</h3>
- Examples of data for a nominal scale include a person's gender, ethnicity, and hair color.
- On the other hand, an ordinal scale requires putting data in a certain order, or in relation to one another and "ranking" each parameter (variable).
<h3>What is the difference nominal and ordinal?</h3>
- Ordinal data has a preset or natural order, whereas nominal data is categorized without a natural order or rank.
- A number that can be measured, however, will always be present in numerical or quantitative data.
<h3>What is an example of a ordinal scale?</h3>
- First place would go to a student with a score of 99 out of 100; third place would go to a student with a score of 92 out of 100; and so on.
