Treat this as an ordinary linear equation. Try to isolate x, as some value. Also remember the basic rules of inequalities: If you're dividing, or multiplying, by a negative, you flip the inequality.
Answer: A or B but really A
Step-by-step explanation:
c² = 144/169
√c² = √144/169
c = 12/13
or
-12/13² = 144/169
Hope that helped! I recommend choosing A
If the series is made up of numbers in an arithmetic progression, you have

where

is the first term and

is the common difference between terms.
Since the last term in the series is

, you have

Solve the system

and you'll find that the first term is

(with

).
Answer:
14
Step-by-step explanation:
Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.
Answer:
The function is correct, I just don't see a question.
Step-by-step explanation: 6 21 6 10
C(n) = 12n + 65
I will make up a question. How much will it cost 4 people each to rent the cabin?
C(n) = (12n + 65) / n n = 4
= (12 × 4 + 65) / 4
= (48 + 65) / 4
= 113 / 4
= $28.25
If your question is differnt just substitute the number of people into the question and solve for C(n)
