n mathematics, a negative number is a real number that is less than zero. Negative numbers represent opposites. If positive represents movement to the right, negative represents movement to the left. If positive represents above sea level, then negative represents below level. If positive represents a deposit, negative represents a withdrawal. They are often used to represent the magnitude of a loss or deficiency. A debt that is owed may be thought of as a negative asset, a decrease in some quantity may be thought of as a negative increase. If a quantity may have either of two opposite senses, then one may choose to distinguish between those senses—perhaps arbitrarily—as positive and negative. In the medical context of fighting a tumor, an expansion could be thought of as a negative shrinkage. Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature. The laws of arithmetic for negative numbers ensure that the common sense idea of an opposite is reflected in arithmetic. For example, − − 3 = 3 because the opposite of an opposite is the original thing.
Divide AB from both sides to isolate the C
D = ABC
D/AB = ABC/AB
C = D/AB
C = D/AB is your answer
hope this helps
C^2 - 10c = 0
c^2 - 10c + 25 = 25
(c - 5)^2 = 25
c - 5 = sqrt 25
c = 5 (+-) sqrt 25
c = 5 (+-) 5
c = 5 + 5 = 10
c = 5 - 5 = 0
solutions are 0,10
In fraction that would be 3/4 because 15/20 simplified would be three quarters.
If thats not the answer, message me back and I will go out of my way to figure out the correct one. Thats my policy :)
