Answer:
x=3
Step-by-step explanation:
2(3x+5)=22+5x-3x.
combine 2 with the bracket
6x+10=22+5x-3x
-10 -10
------------------------------
6x=12+5x-3
first combine 5x and -3x
6x=12+2x
-2x -2x
--------------------------
4x=12
divide by 4
4x/4=12/4
x=3
So the snail nets 8 cm - 1.5 cm = 6,5 cm per day.
Then y = 6.5x where x = number of days.
When y = 275, x = 42.3 days or rounding up, 43 days.
Answer: The elevator takes 20 seconds to travel from first floor to sixteenth floor.
Step-by-step explanation: Given that an elevator takes 4 seconds to travel from the first floor to fourth floor.
We are to find the time taken by the elevator to travel from first floor to the sixteenth floor.
Number of floors between first floor and fourth floor = 4 - 1 = 3,
and
number of floors between first floor and sixteenth floor = 16 - 1 = 15.
So, time taken by the elevator to travel 3 floors = 4 seconds.
Time taken by the elevator to travel 1 floor 
Therefore, time taken by the elevator to travel 15 floors will be

Thus, the elevator takes 20 seconds to travel from first floor to sixteenth floor.
I believe it would multiplication because if Karim wrote 4 times as many as Aviva you would want to know what the 4times of 8 which would be 32.
