Answer:
B. is dependent
Step-by-step explanation:
The denominator determinant will be zero when the coefficients of the variables are dependent. One of the numerator coefficients will be zero when the coefficients involved are dependent. Hence using Cramer's Rule will result in the ratio 0/0 when the system is dependent.
___
The ratio will be 1/0 if the system is inconsistent (has no solution).
2. 2 5/12
4. 1 1/6
5. 1 1/2
6. 1 1/12
7. 1 5/12
8. 1 1/2
9. 1 7/12
10. 1 5/8
Answer:
x=10
50 and 40
Step-by-step explanation:
The sum of the angles of triangle is 180
90 +5x+4x = 180
Combine like terms
90 +9x =180
Subtract 90 from each side
9x = 180-90
9x = 90
x = 90/9
x = 10
The angles are 5x = 5*10 =50 and 4x = 4(10)= 40
Answer: Never true. 24 times 12 is 288, however the LCM for them is 3. 8 times 20 is 160, however the LCM for them is 2.
Step-by-step explanation:
If you look at it by the fact that every number has a LCM of 1, and every even number has an LCM of 2, it is easy to take that and apply it to this question. Just factor in the numbers.
