Ms. griffith lives on one of the highest floors in her apartment building. the elevator goes up one floor every 10.2 seconds. along the way, it stops for a total of 45.8 seconds for people to get out. if it takes her 158 seconds to travel from the lobby to her apartment, what floor does she live on?

Ms. Griffiths lives on 3rd floor

Step-by-step explanation:

The elevator moves 10.2 seconds from one floor to another and stops for 45.8 seconds for people to exit. Thus, add: 10.2 seconds + 45.8 seconds = 56 seconds

If it takes her 158 seconds to travel from the lobby to her apartment, then 158 seconds/56 seconds = 2.8 = 3 (approximately).

Therefore, she lives on 3rd floor.

Mathematically, the values ought to be 168 seconds /56 seconds = 3.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
