Answer:
D. 
Step-by-step explanation:
First, move the variable (+ 2y) to the left-hand side and change its sign.
Then, move the constant (+ 7) to the right-hand side and change its sign.
Then, collect the like terms (y - 2y)
Finally, add the numbers (3 + 7). That will get you your final answer.

Answer:
(6, 4)
Step-by-step explanation:
The midpoint is found as the average of the coordinates of the end points.
M = (A +B)/2
M = ((9, 1) +(3, 7))/2 = (9+3, 1+7)/2 = (12, 8)/2
M = (6, 4)
The midpoint of segment AB is (x, y) = (6, 4).

Answer:
What is the perimeter of a rectangle that is 18 inches wide and 23 inches long?
P = 2(l+w)
l = 23, w = 18
P = 2(23 + 18)
P = 2(41)
P = 82
So the perimeter of the rectangle is 82 inches.
Hope this helped! Have a great rest of your day! :)
