If 2x=4 what is the value of x
Answers
2x = 4
Divide each side of the equation by 2:
x = 2
then
x=4/2
x=2
hence the value of x is 2

The expression (1/2)[x+10] represents the one half of the sum of a number and 10.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
We have:
One half of the sum of a number and 10
Let's suppose the number is x:
So from the problem, the one half of the sum of a number and 10 is:
The above expression represents the one half of the sum of a number and 10.
Thus, the expression (1/2)[x+10] represents the one half of the sum of a number and 10.

y=3-2cos(3x+pi)
Answers
The 3 isn't part of the function's amplitude ... the function wiggles between 2 under it
and 2 over it.
The period of the function is the change in 'x' that adds (2 pi) to the angle.
When x=0, the angle is pi
When the angle is (3 pi) . . .
3 pi = 3x + pi
2 pi = 3x
x = 2/3 pi The period of the function is 2/3 pi .
When x=0, the function is cos(pi) rather than cos(0).
So the function is a cosine with a phase shift of +pi.
It could also be described as a sine with a phase shift of -pi/2 or +3pi/2 .

Answer:
27/3 = 9
Step-by-step explanation:
"How many times does 3 go into 27?" is the same as asking "How much is 27 divided by 3?" Thus, the answer can be calculated as follows:
27/3 = 9"How many times does 3 go into 27?" is also the same as asking "What (x) do you multiply by 3 to get 27?" We solve the problem with an easy algebra equation:
3(x) = 27
x = 9
Tip: When you get a question like "How many times does 3 go into 27?", just think of it as how many times you can fit 3 into 27.

B. The sum of the areas of Square N and Square L is greater than the area of Square K.
C. The sum of the areas of Square N and Square K is equal to the area of Square L.
D. The sum of the areas of Square N and Square K is less than the area of Square L.
Answers
The sum of the areas of Square N and Square L is equal to the area of Square K and this can be determined by using the Pythagorean theorem.
Given :
The diagram shows three squares that are joined at vertices to form a right triangle.
The following steps can be used in order to determine which statement is true:
Step 1 - The Pythagorean theorem can be used in order to determine which statement is true.
Step 2 - According to the Pythagorean theorem, the sum of the square of the shorter sides is equal to the square of the longer side.
Step 3 - So, from the above steps, it can be concluded that the sum of the areas of Square N and Square L is equal to the area of Square K.
Therefore, the correct statement is given by option A).

Answer:
the population of Florida
Step-by-step explanation:
A value that varies means a value that shall change over a period of time.
Accordingly when we talk about population the population shall increase or decrease with time, as this the natural thing that new babies are born and at the same time people also die.
Even in Florida there will be new babies who are born and also there shall be people who might be dying. Accordingly the population count keeps on changing.
The flight time depends upon the aerial distance and the speed which generally remains same.
Accordingly if a flight takes hours to travel the distance it will be same.
The area of a particular place shall not change as earth will not create new land, or the area will remain same by any how only exception to this is acquisition of land of neighbouring places, by war or political influence, but not in a natural manner.
Thus, population of Florida is variable.
Final answer:
The flight time from Philadelphia to San Francisco varies.
Explanation:
The subject of the question is a comparison of three different values: the population of Florida, the area of Colorado, and the flight time from Philadelphia to San Francisco. Out of these three, the value that varies is the flight time from Philadelphia to San Francisco.
This is because the population of Florida remains relatively constant over time, while the area of Colorado also remains the same. However, the flight time from Philadelphia to San Francisco can vary based on factors such as weather conditions, air traffic, and flight routes.
For example, if there are strong headwinds, it may take longer to fly from Philadelphia to San Francisco compared to a day with favorable tailwinds.
