Answer:
The solution to the system of linear equations is (1,9).
Step-by-step explanation:
The given system of linear equations
... (1)
.... (2)
Subtract equation (2) from equation (1) to eliminate y.
On combining like terms, we get
Add 8 on both sides.
Divide both sides by 8.
The value of x is 1.
Substitute x=1 in equation (1).
The value of y is 9.
Therefore the solution to the system of linear equations is (1,9).
Its true because scalene doesn't have equal sides

<h3>
Answer: Total price of all 5 cars = $35000.</h3>
Step-by-step explanation:
We are given total number of cars = 5 cars.
The mean of all of five cars = $7000.
Note: Total sum/value could be calculated by multiplying mean with the total numbers we have.
<em>Total price = Mean × Total number of cars.</em>
According to problem, mean is 7000 and total number of cars is 5.
<h3>Therefore, Total price of all 5 cars = 7000 × 5 = $35000.</h3>
