Answer:
The greatest common divisor (gcd) of two or more numbers referst to the largest positive integer that divides each of the integers. Also, two integers are said to be relatively prime, mutually prime, or coprime if the only positive integer that divides both of them is 1. Therefore, If the GCD of 5 and 12 is one, it means that the two numbers are mutually prime.
The correct answer is option D:)
Given the diameter of a circle, we can find its radius by dividing the diameter by 2, like this:

Where r is the radius and d is the diameter of the circle, by replacing 30 for d, we get:

Then, the radius of this circle equals 15 m
That is false!
Try doing it with a number less than 0.
If you square .5

you will get 0.25
0.25 is less than .50
Answer:
different
Step-by-step explanation:
different slopes gives one solution
same slopes with different constant has no solution
same slopes and constants has many solutions
