Answer:
135-x=c
Step-by-step explanation:
135 is what she has, when you subtract (x) which is what she sold, it should give you the amount she has left (c)
Answer
False
Step-by-step explanation:
The max number is 1 and so the unlikelier the number, the less value the number will be.
For example: The likelyhood of fliping a coin and landing on heads: 0.5
Hopes this makes sense!
Rewrite the system of equations in matrix form.
![\begin{bmatrix}1&2&-2\\3&7&-1\\2&4&m\end{bmatrix} \mathbf x = \mathbf b](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D1%262%26-2%5C%5C3%267%26-1%5C%5C2%264%26m%5Cend%7Bbmatrix%7D%20%5Cmathbf%20x%20%3D%20%5Cmathbf%20b)
This system has a unique solution
so long as the inverse of the coefficient matrix
exists. This is the case if the determinant is not zero.
We have
![\det(\mathbf A) = m+4](https://tex.z-dn.net/?f=%5Cdet%28%5Cmathbf%20A%29%20%3D%20m%2B4)
so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.
Answer:
Marcy's math class starts at 9:35.
Step-by-step explanation:
11:55
-50 = 11:05 This gets rid of 50 minutes of math class.
11:05
-30 = 10:35 This gets rid of the 30 minutes of recess.
Now subtract one more hour to subtract the remainder of math class, and you get 9:35. Marcy's math class starts at 9:35.
