An isosceles triangle is a triangle with 2 congruent sides. The congruent sides are called legs and the third side is called the base. So if 2 sides of a triangle have the same length, then we say that the triangle is isosceles.

Answer:
The unique solution to the system is (x,y){(-9,-3)}
Step-by-step explanation:
x - y = -6 equation 1
5x + 6y = -63 equation 2
We will find the value of x from equation 1.
x= y-6
Now put the value of x in equation 2.
5(y-6)+6y = -63
5y-30+6y = -63
Combine the like terms:
5y+6y= -63+30
11y = -33
Divide both sides by 11.
11y/11 = -33/11
y = -3
Now put the value y = -3 in x=y-6
x = y-6
x= -3-6
x= -9
Therefore The unique solution to the system is (x,y){(-9,-3)} ....
<u>Given</u>:
A map shows some cities in the northern United States. The scale of a map is 
The actual distance between Chicago, IL and Pittsburgh, PA is 375 miles.
We need to determine the distance between the two cities on the map.
<u>Distance between the two cities:</u>
The distance between the two cities on the map can be determined by dividing the actual distance by 125 miles.
Thus, we have;
Dividing the terms, we get;
Thus, the distance between the two cities on the map is 3 inch.
