Answer:
The mistake is that 4x+x = 5x not 4x
Step-by-step explanation:
4x + x = 30 –6
Combine like terms
5x = 24
Divide each side by 5
5x/5 = 24/5
x = 24/5
The mistake is that 4x+x = 5x not 4x
Answer:
Step-by-step explanation:
this is the equation used to find the average of two numbers.
Let's write the function that represents the problem:
ax = 210x + 240
We are going to evaluate the first five nights:
a0 = 210 * (0) + 240 = 240
a1 = 210 * (1) + 240 = 450
a2 = 210 * (2) + 240 = 660
a3 = 210 * (3) + 240 = 870
a4 = 210 * (3) + 240 = 1080
We then have the following terms:
240, 450, 660, 870, 1080
We observe that the common difference of the terms is:
210
Therefore, since they have the same common difference, we are facing an arithmetic sequence.
Answer:
A the situation represents an arithmetic sequence because of the successive and values have a common difference of 210
Answer:
Before solving the given trigonometric relation change everything to sines and cosines
Step-by-step explanation:
consider the given equation;
=
Multiplying the above equation on both sides by 
then we get,
By using identity,
expand above equation we will get,
Then,
So the required value of the angle is 
degree.
