Answer:
45
Step-by-step explanation:
Answer: The determinant of the coefficient matrix is -15 and x = 3, y = 4, z = 1.
Step-by-step explanation: The given system of linear equations is :
We are given to find the determinant of the coefficient matrix and to find the values of x, y and z.
The determinant of the co-efficient matrix is given by
Now, from equations (ii) and (iii), we have
Substituting the value of y and z from equations (iv) and (v) in equation (i), we get
From equations (iv) and (v), we get
Thus, the determinant of the coefficient matrix is -15 and x = 3, y = 4, z = 1.
Answer:
sila put a wrong number in her calculator when multiplying the numerators
Step-by-step explanation:
Sila jogged 12 kilometers today and wants to know how far she traveled in feet. what error did sila make while converting from kilometers to feet?
StartFraction 12 kilometers Over 1 EndFraction times StartFraction 0.62 miles Over 1 kilometer EndFraction times StartFraction 5280 feet Over 1 mile EndFraction = 392,832 feet
sila put a wrong number in her calculator when multiplying the numerators.
1 km sila's first fraction should be 0 62 mi 1 mi
sila's last fraction should be 5280 ft
sila forgot to divide by 0 62 asap
(12kilometers / 1 ) × (0.62 miles / 1 kilometer) × 5280 / 1 mile
12 kilometers = 39,370.079 feet
1 kilometer = 0.621 miles
sila put a wrong number in her calculator when multiplying the numerators
