Protons and electrons are 12. For neutrons, there are 12 of them.
<span>Magnesium has an </span>atomic number<span> of 12, which means there are 12 protons.
You subtract the atomic number from the mass number in order to find neutrons.
</span>Atomic mass is 24. 24-12=12
Electrons always match the number of protons.
Answer:
- determinant: -15
- x = 3; y = 4; z = 1
Step-by-step explanation:
The matrix of coefficients has one row corresponding to each equation. The constants in that row are the coefficients of the variables in the equation. Coefficients are listed in the same order on each row. A missing term is represented by a coefficient of 0.
<h3>coefficient matrix, determinant</h3>
The first attachment shows the coefficient matrix and its determinant.
__
<h3>solution</h3>
The solution to the system of equations can be found by left-multiplying the constant vector by the inverse of the coefficient matrix.
This multiplication is shown in the second attachment. It tells us ...
Answer:
The answer to your question is
Step-by-step explanation:
Real operation
Process
1.- Factor the denominators
2.- Simplify like terms
Cancel (x - y) and (x - 1) because they are in numerator and the denominator
This is the answer or you can expand
3.- Expand
If this helps. 2 x 1= 2 then add the two zeroes since there is two zeroes so your answer is 200
