Answer:
x = -5, y = -6, z = -3
Step-by-step explanation:
Given the system of three equations:

Write the augmented matrix for the system of equations

Find the reduced row-echelon form of the augmented matrix for the system of equations:

Thus, the system of three equations is

From the last equation:

Substitute it into the second equation:

Substitute y = -6 and z = -3 into the first equation:

Answer:
that would be 7.33
Step-by-step explanation:
sorry it's 66
I divided 3 by 22 instead of multiplying
Answer:
245
Step-by-step explanation:
$49.00 times 5 is 245. The 5 came from the question because it says a normal work week has 5 days so you would multiply $49.00 by 5
$0.66 / 0.3% = 2.2
Check:
2.2 * 0.3 = 0.66
Hope this helps!
