Answer:
d
Step-by-step explanation:
The expression "n - 10 + 9n - 3" simplifies to "10n - 13".
We have,
To solve the expression "n - 10 + 9n - 3" and combine liketerms, we need to add or subtract the coefficients of similar variables.
First, let's rearrange the expression by grouping like terms:
(n + 9n) + (-10 - 3)
Combining the coefficients of "n," we have:
10n + (-10 - 3)
Simplifying the terms within parentheses:
10n - 13
Therefore,
The expression "n - 10 + 9n - 3" simplifies to "10n - 13".

and B has coordinates (6,3).
The midpoint of A and B where A has coordinates (2,7) and B has coordinates (6,3) is (4, 5)
If B(x, y) is the midpoint of the line segment AC with end points at A(x₁, y₁) and C(x₂, y₂), the coordinates of B is:
x = (x₁ + x₂)/2; y = (y₁ + y₂)/2
Let O(x, y) be the midpoint of A and B where A has coordinates (2,7) and B has coordinates (6,3). Hence:
x = (2 + 6)/2 = 4; y = (7 + 3)/2 = 5
Hence the midpoint of A and B is (4, 5)

Given that the coordinates of the point A is (2,7) and the coordinates of the point B is (6,3)
We need to determine the midpoint of A and B
Midpoint of A and B:
The midpoint of A and B can be determined using the formula,
Substituting the points (2,7) and (6,3) in the above formula, we get;
Adding the numerator, we have;
Dividing the terms, we get;
Thus, the midpoint of the points A and B is (4,5)
