Please show a pic so i can understand better
<span>1. </span><span>So, Sam is building a model of an
antiques car that has a scale to the actual car which is 1:10.
The model that he is creating is 18 and ½ inches long.
We need to find the length of an actual car.
=> the scale is 1:10, in this scale, every inch represent 10 inches in of an
actual car
=> 18 and ½ will be converted into fraction which will be
equals to 18.5
Now, let’s multiply the two numbers
=> 10 x 18.5
=> 185 inches, the length of an actual car is 185 inches long.

Answer:
The solution for this system is:
Step-by-step explanation:
The problem states that we have to solve this system by the elimination method
In the elimination method, we transform the system in such a way that one variable can cancel each other. With this, we find the result of the other variable. Then, we can replace the variable we found in any of the equations, and we have the value of the variable that we had initially canceled.
In this problem, we have the following system:
If we add equations 1) and 2), the variable x is going to be eliminated
Now, we can replace the value of y in any of the equations, to find x:
I will replace in equation 2)
The solution for this system is:
When a negative number is divided by another negative number, <span>sign of the quotient would be positive and always positive</span>
