Final answer:
To verify the equation 6(20/7)-9-2(1-(20/7))=(20/7)+9, we simplify both sides and show that they are equal. After calculation, the equation is verified to be true.
Step-by-step explanation:
To verify the equation 6(20/7)-9-2(1-(20/7))=(20/7)+9, we need to simplify both sides of the equation separately.
For the left side of the equation:
6(20/7)-9-2(1-(20/7))
=6(2 5/7) - 9 - 2(1 - (2 5/7))
=6(40/7) - 9 - 2(7/7 - 40/7)
=240/7 - 9 - 2(7 - 40)/7
=240/7 - 9 - 2(-33)/7
=240/7 - 9 + 66/7
=(240 - 63 + 66)/7
=243/7
For the right side of the equation:
(20/7) + 9
=20/7 + 63/7
=(20 + 63)/7
=83/7
Since the left side of the equation equals the right side of the equation (243/7 = 83/7), the equation is verified to be true.
