The solution of the system of equation of the matrix is as follows:
x = - 8
y = 3
<h3>How to find the solution of matrix?</h3>
3x + 10y = 6
x + 3y = 1
multiply equation(ii) by 3
3x + 10y = 6
3x + 9y = 3
Therefore,
y = 3
Hence,
x + 3y = 1
x + 3(3) = 1
x + 9 = 1
x = 1 - 9
x = -8

Well if 6 min to 16 min is a ratio it would be 6:16 then simplified to 3:8 and then made into a fraction would be 3/8
The appropriate expression is x'y'z, where the apostrophe indicates the complement of the variable.
Answer:
The cost of the television is
Step-by-step explanation:
Let
x -----> the cost of the television in dollars
we know that
The cost of the television represent 100%
<em>If Matt pays cash</em>
then
so
The cost is 0.93x
<em>If Matt pays with a loan</em>
then
so
The cost is 1.1x
The difference between the two methods is
Remember that
The difference between the two methods is $49.98
so
Solve for x
It would be: 158/4 = 39.5 = 39 1/2
So, your final answer is 39 1/2
Hope this helps!
