The wall is 20ft deep, the snail goes up 4ft every day and drops 2 ft every night. how many days does it take the snail to reach 20ft?

It takes the snail 10 days to reach 20 ft because if it loses 2 ft of the 4ft it climbs every day you can just calculate 20/2 and get 10 instead of 20/(4-2)

the snail will actually take 9days to reach the wall

hopefully this helped you

have a amazing nite or day

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

25/14 or 1.
