Answer:
They will have values in common
Step-by-step explanation: I GUESSED
First, distribute the 7:
7w + 14 + 0.5w = 5
Combine like terms:
7.5w + 14 = 5
7.5w = -9
Divide both sides by 7.5 to solve for w:
w = -9/7.5 = -1.2
The answer is -1.2
The formula that describes this function is c = 50t
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let c represent the distance travelled at time t.
The cities are 200 miles apart and constant speed of 50mph, hence:
50 = c/t
c = 50t
The formula that describes this function is c = 50t

For this case we have the following system of equations:
We can Rewrite the system of equations of the form:
Where,
A: coefficient matrix
x: incognita vector
b: vector solution
We have then:
![A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]](https://tex.z-dn.net/?f=%20A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%263%5C%5C-8%26-3%5Cend%7Barray%7D%5Cright%5D%20%20)
![x=\left[\begin{array}{ccc}x\\y\end{array}\right]](https://tex.z-dn.net/?f=%20x%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%20)
