Given:
Two numbers are 12 and 21
To find:
The factors of 12 and 21, then find the common factor and the greatest common factor.
Solution:
Two numbers are 12 and 21. The prime factors of these two numbers are
From the above factorization, it is clear that the factor 3 is common in both. So,
Common factor (CF) = 3
Only 3 is common in factorization of both. So,
Greatest common factor (GCF) = 3
Therefore, the common factor is 3 and the greatest common factor is also 3.
Answer: Third option
Step-by-step explanation:
One of the ways of solving a system of equations is by equating the equations and solving for one of the variables.
In this case we have the system:
Note that if 
is equal 
and also equals 
Then logically must be equal to .
We write equality.
Then the correct answer is the third option.
We can also solve for the variable x
The minimum function determines the lowest number in a range!
Answer:
x= 6
Step-by-step explanation:
Isolate all variables on their own and numbers on the other
5x -4x +7-7 = -1 +7 +4x -4x
5x -4x = -1+7
Solve for x
x = 6
Answer:
Step-by-step explanation:
A proportion is needed to find the value of x
