It's suppose to add 450mph+250mph=700 then divide 3 hours=233.3
The solution for the given system of equations x + 8y = -37, 4x + 8y = -52 is
Given,
System of equations as,
x + 8y = -37
4x + 8y = -52
We have to solve this by using the inverse of coefficient matrix of the equivalent matrix equation.
That is,
Now we can solve the equations.
Here we have,
x + 8y = -37
4x + 8y = -52
Now in matrix form,
A X B
We know that,
Therefore,
Then,
That is

x + 8y = -37
4x + 8y = -52
Answer:
Step-by-step explanation:
• Suppose the angle is PQR where Q is the midpoint.
• Keep the compass at angle vertex Q and adjust some wide setting (the width is not important).
• Without changing the compass, draw an arc across each leg of the angle
• Now keep the compasses on the point drawn on each leg, and draw an arc in the interior of the angle.
• Using a ruler, draw a line through the vertex to the point where the arcs cross
If you do simple division for one adult ticket, such as what I did, 4/47, it gave me 11.75, so I went with eleven, then I multiplied until I couldn't then counted up the extras and got 3 dollars for a child ticket, to make sure yo;u do it with the next number and you have your answer; $11 adult, $3 kid... hope this helps!
The solution of 4x - 8 + 3x = 49 - 73 + 4x - 1 + 2 is equal to
<u>Solution:</u>
Given, equation is 4x – 8 + 3x = 49 – 73 + 4x – 1 + 2
We have to solve the above given equation for x.
Now, take the given equation.
4x – 8 + 3x = 49 – 73 + 4x – 1 + 2
Adding the like terms we get,
7x – 8 = - 14 + 4x + 1
7x – 4x = - 14 + 1 + 8
3x = - 14 + 9
3x = - 5
Hence, the value of x is
