Answer: A
Step-by-step explanation:
Answer:
1 2/3
Step-by-step explanation:
well first reduce it which would be 5/3 since the greatest common denominator would be 4. Then put 3 in the 5 which goes only once and 2 is left over. Keep the threeas the denominator instead of the numerator.
Answer
(a)
(b)
Step-by-step explanation:
Remember that when you want to solve a problem like this, you express the equation as following
So, if you know the inverse of then
For this case
Now for this case the inverse of A would be
Then when you multiply with the vector solution
So from that information you can conclude that the solution to the system of equations is x = 500/7 y = 2400/7 and z = 2700/7
