Help me please my test is gonna end in 30 minutes

i believe it is -7 degrees. 13-20=-7

pro tip: "big minus small takes the sign of the big" is how i remember negative numbers.

20 is the bigger than 13, and when you subtract them you get 7. 20 has a negative, so 7 takes "the sign of the big", making it -7

The answer is -7

Step-by-step explanation:

Because if you started at positive 13 and it dropped 20 degrees, it would be negative 7.

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.
