The only way this could be true is under one of the following conditions:
- a, b and c are all equal to zero
- b is equal to 1 and a is equal to c
- b is equal to -1 and a is equal to -c
Consider:
ab = c
bc = a
First, plug the second equation into the first one to find the value of b:
(bc)(b) = c
b2c = c
b2 = 1
b = ±1
Now take those values and plug it into either equation:
(1)(c) = a
c = a
or:
(-1)(c) = a
c = -a
To prove that the absolute values of c and a must be identical:
Given:
ab = c
bc = a
Then:
ab/c = 1
bc/a = 1
Therefore:
ab/c = bc/a
a2b = bc2
a2 = c2
|a| = |c|

What is the associative property of multiplication?
The Associative property of multiplication states that the product of a set of three numbers is always the same no matter which operation is carried out first.For example Ax(BxC) = (AxB)xC and so either can be written as AxBxC.ie 3x(4x5) = 3x20 = 60and (3x4)x5 = 12x5 = 60It is important not to confuse this with the commutative (or Abelian) property which states that the order of the numbers does not matter. ie AxB = BxAMatrix multiplication, for example, is associative but NOT commutative.(a * b) * c = a * (b * c)As a result, we can write a * b * c without ambiguity.

AXC and BXC form a linear pair True or false?
The answer depends on where the points A, B, C and X are. And since you have not bothered to provide that information, I cannot provide a sensible answer.
What is the solution of 3x plus 7y-c equals?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
If A squared plus B squared equals C squared and C equals 70 what is A and B?
The solution follows A=42 42X42=1764 B=56 56X56=3136 sum of above=4900 (70X70=4900) Given you was looking for C and not C squared. Try A and B and doublecheck it for me.
What are all of the multiplicative identities?
AxB=BxA (AxB)xC=Ax(BxC) Ax(B+C)=AxB+AxC Ax1=A Ax0=0
What does bxc equal?
It equals b times c.
Can you multiply a 2x2 matrices?
You can definitely multiply 2x2 matrices with each other. In fact you can multiply a AxB matrix with a BxC matrix, where A, B, and C are natural numbers. That is, the number of columns of the first matrix must equal the number of rows of the second matrix--we call this "inner dimensions must match."

What does b times c equal?
Well, darling, b times c equals the product of b and c. In other words, you multiply those two numbers together to get your answer. Math can be a real hoot, can't it?

What is the solution to this equation -5c plus 31 equals 1?
The value of c is 6
What is the solution for -15 plus c plus 5 equals 75?
-15+c+5 = 75 c = 75+15-5 c = 85
What is the simplified solution to BC plus 0 equals f?
f = B x C
Which solution is the most acidic A. apple juice pH equals 3 B. pure water pH equals 7 C. hand soap solution pH equals 10 D. drain cleaner solution pH equals 14?
The most acidic solution is D. drain cleaner solution with a pH of 14. The lower the pH value, the more acidic the solution is. In this case, a pH of 14 indicates a highly alkaline or basic solution, not acidic.
A is 2 B is 4 what is c?
"6" It all depends on the relationship between A B and C. EG if a+b=c the c=6, if axb=c then c=8. you can throw in allsorts of relationships C/A = B So more information is required in the question
