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.
Answer: 7x-y=10
Step-by-step explanation:
It should be 6.36cm. If not ask someone smart in your class.
55 minus 18 is 37 and then it would be 37,000 and then you just convert it so it is 37% of 100 (the answer is 37%)
14) The sum of anything and its additive inverse is zero. (That is the definition of additive inverse.) The appropriate choice is ...
... A) equal to 0
