Answer:
n = 3
Step-by-step explanation:
Ratio from Triangle A to Triangle B is 2:1.
n+2 = 5
n = 3
Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
Hey there! :)
Answer:
(3.5, -1).
Step-by-step explanation:
Use the midpoint formula to solve this problem:

Plug in the coordinates given:

Simplify:

Therefore, the coordinates of the mid-point are:
(3.5, -1).
3/4+1/3=9/12+4/12=13/12 of an hour
13/12= 1 1/12
