2 1/7= 15/7 5 2/5= 27/5. Then with the numbers 14/3, 15/7, 27/5, you would multiply them, and you would get 5670/105. That simplifies to 54
Answer:
BC= 4x-10
Step-by-step explanation:
Mid-point is the center position of a segment. It is half the length of the segment.
Given the segment as AC =8x-20
and B is the midpoint of AC, then BC is half the length AC
1/2( 8x-20)= 4x-10
BC= 4x-10
