Answer:
L= 24cm
W= 4cm
Step-by-step explanation:
Given data
Perimeter= 56cm
Area= 96cm^2
Let the width be x
W= x cm
L= 5x+4
P=2L+2W
56= 2(5x+4)+2x
56= 10x+8+2x
56-8= 12x
48= 12x
x= 48/12
x= 4cm
L= 5x+4
L= 5(4)+4
L= 20+4
L= 24cm
Answer:

Answer:
y=100x+18
Minutes included over the cost of plan
cost of plan starts
Step-by-step explanation:
Answer:
y = 8
x = 9
Step-by-step explanation:
given equation,
x + y = 17 ........(1)
9 x - y = 73...........(2)
writing in matrix form
A X = B
![\begin{bmatrix}1 &1 \\ 9 &-1 \end{bmatrix} \begin{bmatrix}x\\ y\end{bmatrix}=\begin{bmatrix}17\\73 \end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D1%20%261%20%5C%5C%209%20%26-1%20%5Cend%7Bbmatrix%7D%20%5Cbegin%7Bbmatrix%7Dx%5C%5C%20y%5Cend%7Bbmatrix%7D%3D%5Cbegin%7Bbmatrix%7D17%5C%5C73%20%5Cend%7Bbmatrix%7D)
using augamented matrix A|B
![\begin{bmatrix}1 &1& 17\\ 9 & -1 & 73\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D1%20%261%26%2017%5C%5C%209%20%26%20-1%20%26%2073%5Cend%7Bbmatrix%7D)
using row transformation
R₂ = R₂ - 9 R₁
![\begin{bmatrix}1 &1& 17\\ 0 & -10 & -80\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D1%20%261%26%2017%5C%5C%200%20%26%20-10%20%26%20-80%5Cend%7Bbmatrix%7D)
now,
![\begin{bmatrix}1 &1 \\ 0 &-10 \end{bmatrix} \begin{bmatrix}x\\ y\end{bmatrix}=\begin{bmatrix}17\\-80 \end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D1%20%261%20%5C%5C%200%20%26-10%20%5Cend%7Bbmatrix%7D%20%5Cbegin%7Bbmatrix%7Dx%5C%5C%20y%5Cend%7Bbmatrix%7D%3D%5Cbegin%7Bbmatrix%7D17%5C%5C-80%20%5Cend%7Bbmatrix%7D)
now
-10 y = -80
y = 8
and
x + y = 17
x = 17 -8
x =9
20% of $500 = 100$ so we take off 100.
And we take off $50 because it was out of the box and slightly scratched.
So result is $500 - $100 = $400
$400-$50 = $350
Answer = $350
Equation:
Let’s say
500=X
100=Y
50=Z
And answer = A
A=X-(Y-Z)
I hope this will be helpful
