Call M the midpoint. The coordinate of this point is given by....
M=(x1+x2 /2, y1+y2 /2)
So (3,7)=(x1+0 /2, y1+ -5 /2). or
3= x1/2. or x1=6 and
7=y1-5 /2. or 14=y1-5 or y1=19
B is at the point (6,19)

____________________________________________________Explanation:____________________________________________________Given:
____________________________________________________ 2 / (9x) = 4 / 7 ; solve for "x" ;
____________________________________________________Cross-multiply:
→ (9x)*4 = 2 * 7 ;
→ 36x = 14 ;
Divide each side of the equation by "36" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 36x / 36 = 14 / 36 ;
x = 14/ 36 ;
→ x = 14/36 = (14÷2) / (36÷2) = 7/18 ;

Answer:
1. 11/4
2. 19 1/4
Step-by-step explanation:
To change into an improper fraction:
((2 times 4)+3)/4
=11/4
To calculate total distance:
(11/4) times 7
=77/4
=19 1/4
Answer:
60°
Step-by-step explanation:
since all sides of a triangle are equal .The given triangle is an equilateral triangle. And each angles of an equilateral triangles is 60 degree.So angle A is also 60 degree.
