The radius is half the diameter, so the formula would be r=d divided by 2
Answer: The set does not have a solution
Step-by-step explanation:
Adding Equations 1 & 3 we get 5x = 7. This gives x = 7/5
Putting this value of x in eq. 2 we get
-2y + 2z = -1-(7/5) or
2y - 2z = 12/5 or 5y - 5z = 6
Multiplying eq. 1 by 2 we get
4x + 2y - 2z = 6
adding this with eq. 2 we get 5x = 5 or x = 1
As the common solution for x from equations 1&3 does not satisfy eq. 1&2 it comes out that the three equations do not have a common solution.
Same can be verified by using different sets of two equations also.

Step-by-step explanation:
i cant assure that all of them are right but mostly all of them are
Step 3 is wrong . Jorge incorrectly applied the addition and subtraction properties of equality
The answer is the fraction is 66/100 or simplified, 2/3<span />
