Four is equal to half of the sum of a number n and 22. What is the number n ? n = 30 n = 24 n=−14 n=−20.
Answer:
The answer is n = -14 .
Step-by-step explanation:
4 = 1/2(n + 22)
4 = 1/2n + 11
-7 = 1/2n
-7 / 1/2 = -14 = n
To check your work:
4 = 1/2(-14 + 22)
4 = 1/2(8)
4 = 4

What is an arrangement?An arrangement is a permutation of a set of objects in mathematics where the order of the things is important. An arrangement is specifically an orderly succession of unique elements drawn from a set.
Consider the set "A, B, C," for instance. This set can be arranged in six different ways: ABC, ACB, BAC, BCA, CAB, and CBA. The three components of the set are stated in a precise order in each of these configurations.
The number of ways that 7 students can be arranged in a line is 7! (7 factorial) which is equal to:
7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5,040
Therefore, there are 5,040 different ways that the first seven students in line can be ordered.

What is the simple interest?Simple interest rate is the interest that is paid only on the principal portion of a loan. This means that the debtor does not pays interest on the interest rate already accrued.
Simple interest = principal x time x interest rate

Answer:
26 degrees
Step-by-step explanation:
Triangle A:
So the triangle is 24 degrees and it is an isosceles triangle so the other 2 angles are equal. All the angles in a triangle add up to 180 degrees.
180-24=156 degrees
156 divided by 2 because of the 2 angles = 78 degrees
The angles in Triangle A are 78 degrees which means one corner of the Triangle X is 78 degrees as it is vertically opposite.
Triangle B:
B= 49 degrees and the triangle is isosceles as well. 49 x 2 for the other angle which would be the same is 98 degrees. We would then do
180 -98 = 82 degrees
This means the other angle in Triangle X is 82 degrees
Triangle X:
72 degrees is the top left angle and 82 degrees is the top right angle so you do 72+82= 154 degrees
180-154= 26 degrees

if ac = 8x 14 and ec =2x + 11 solve for x
Equivalent expressions are expressions that have equal values
The value of x is 25/6
How to calculate the value of xFrom the question, the values of ac and ec are equivalent
So, we have:
8x - 14 = 2x + 11
Collect like terms
8x - 2x = 14 + 11
Evaluate the like terms
6x = 25
Divide both sides by 6
x = 25/6
Hence, the value of x is 25/6

The total cost of four pens and six mechanical pencils is $16.20. The cost of each pencil is 70 cents. Using an arithmetic approach, find the cost of a pen.
Answer:
300 cents or $3
Step-by-step explanation:
Let p be the cost of one pen and m be the cost of one mechanical pencil. We can use this to set up a system of equations:
4p+6m=1620 (convert $16.20 to cents by multiplying it by 100)
m=70
We can solve this using substitution (substitute 70 for m):
4p+6(70)=1620
4p+420=1620
Subtract 420 from both sides
4p=1200
Divide both sides by 4
p=300 cents or $3
