Answer:
eh just to be honest it would be b for a 11 year old doing 7 to college stuff
Step-by-step explanation:
Multiply both sides by 2 to get rid of the fraction. then, subtract p from both sides to isolate m. therefore the answer would be [m= 2B-p]
Step-by-step explanation:
If 21 is not repeating, then it's easy.
If If 21 is repeating, then the solution is:
Answer:
x=-1/85; y=-283/85; z=2/17
Step-by-step explanation:
Using an algebraic method like elimination or substitution would take a lot of steps which could lead to mistake the calculations. In this case, I decided to use the Gaussian elimination. We can express the system in matrix form as follows:
To begin the calculations, we write the system in augmented matrix form and use the Gaussian elimination:
By applying the Gaussian elimination, the final matrix is the following:
In order to verify the results, it´s enough to substitute the calculated values in the original equations to see if the equalities are correct. Here you can see the verification for all of the equations:
