Answer:
1) A system of two linear equations to represent this problem
x+y=20 and x-y=12
2) The numbers are x=16 and y=4
Step-by-step explanation:
Let x and y be the two numbers
Given that the sum of the two numbers is 20
That is 
and the difference is 12
That is 
1) A system of two linear equations to represent this problem


2). Noe Solve the system to find the 2 numbers:
Adding the equations (1) and (2) we get


_____________
2x=32

Therfore x=16
Now substitute x=16 in equation (1) we get


Therefore y=4
Therefore the numbers are x=16 and y=4
Step-by-step explanation:
Statement:
"If two sides of a triangle are congruent, then the angles opposite of them are congruent"
Converse:
If two angles of a triangle are congruent, then the two sides opposite them are congruent.
The converse of the statement is true and can be proven true using a two-column proof. In fact it is a theorem.

Step-by-step explanation:
Answer: (-28/3 , -2/3)
Step-by-step explanation: Given the
coordinates of the point on the directed line segment from (−6,−6) to (-4, 10)
(X2 -X1) , (Y2 - Y1)
(-4-6) , (10- - 6)
-10, 16
To partitions the segment into a ratio of 1 to 3?
-10×1/3 , 16×1/3
-10/3 , 16/3
The answer will be
(- 6 - 10/3) , (-6 +16/3)
(-28/3 , -2/3)
