Answer: The second matrix
If we want to write a proper matrix to represent the given system of equations, we have to arrange it in order:
After this, we can write the matrix with the coefficients of each equation:
![\left[\begin{array}{ccc|c}1&1&1&180\\2&-1&0&0\\4&0&-1&-5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Cc%7D1%261%261%26180%5C%5C2%26-1%260%260%5C%5C4%260%26-1%26-5%5Cend%7Barray%7D%5Cright%5D)
Being this, the matrix that represents the measure of each angle in Ming's triangle
Can you try to put it more in order?
Using the given information find the length and width of the base:
Perimeter = 2L + 2W
L = 3W
Replace L in the first equation:
Perimeter = 2(3W) + 2w
96 = 2(3W) +2W
Simplify:
96 = 6W +2W
96 = 8w
Divide both sides by 8:
w = 96 / 8
w = 12
The width is 12 inches.
The length = 3 x 12 = 36 inches.
Volume = L x W X H
Volume = 36 x 12 x 14
Volume = 6,048 cubic inches.
Answer:
y = 1/2x - 1
Step-by-step explanation:
The x value is divided by 2 and then has 1 subtracted from it.
also for future posts, put the question in the title that way people know what you need and can click if they know the answer.
Answer:
your answer is 20 because you subtract 110 by 90 because that is a right angles and all right angles are 90 degrees.
