Answer:
2x + 8 = 12
x = 2
4x = 2 = 10
Step-by-step explanation:
Find the polar coordinates in the usual way, then negate r and add 180° to θ.
You know that
... r = √(x² + y²)
... θ = arctan(y/x) . . . . . taking quadrant into account
The coordinates (r, θ) and (-r, θ+180°) specify the same point.
|-5| - |7 - 4|
First, simplify |-5| to 5. / Your problem should look like: 5 - |7 - 4|
Second, simplify 7 - 4 to 3. / Your problem should look like: 5 - |3|
Third, simplify. / Your problem should look like: 2
Answer: 2
Let the number be x
So 12% of x
= 0.12 of x
= 0.12x
Also 10 % of 6
= 0.10 of 6
= 0.10 ×6
= 0.6
Now 12% of x is the same as 10% of 6.
So
Now as both represent the same quantity
So 0.12x = 0.6
Dividing both sides by 0.12
We get
x = 0.6 / 0.12
x= 5
Hence 12% of 5 is the same as 10% of 6
Answer:
Real numbers include all decimal fractional, negative and positive integers, whereas the complex number can be written as the sum of difference of a real and imaginary numbers.
