16. The quotient of a number and -2 is the same as the sum of -4 and 10.

The number is -12

Step-by-step explanation:

The situation can be represent by the equation  

      Now solve for n   by combining like terms on the right side

= 6     multiply both sides by -2  

n = -12

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
