The sum of two numbers is 167. The second number is 29 less than three times the first number. Fine the numbers. The two require
2 answers:
Answer:
Step-by-step explanation:
Let the first number be
Let the second number be
Applying substitution method.
Combining like terms.
Adding 29 to both sides.
Dividing both sides by 4.
Substituting x = 49 for the second equation.
Multiplying the numbers.
Subtracting.
The two required numbers are 49 and 118.

- The Midpoint of AB is (1,0).
Given that:
- In line AB, where the coordinates of A is (3,1) and coordinates of B is (-1,-1).
To find:
- The Midpoint of line AB.
So, according the question
We know that,
The midpoint M of a line segment AB with endpoints A (x₁, y₁) and B (x₂, y₂) has the coordinates M ( ).
Now from question,
We know that the the coordinates of A is (3,1) and coordinates of B is (-1,-1) of line AB.
So, we can say that
A is (3,1) or x₁ = 3 and y₁ = 1.
B (-1,-1) or x₂ = -1 and y₂ = -1.
∵ The coordinates of midpoint M (X,Y)
X =
=
= 2/2
X = 1.
And
Y =
=
= 0/2
Y = 0.
So, the midpoint of line AB is M (1,0)
