A full water tank holds 500 litres.
The tank begins to leak water and is losing 14% of its contents every hour. Find how much water is left in the tank after 8 hours.

0 Litres

Step-by-step explanation:

If the tank holds 500 litres and its loosing 14% every hour, just multiply

14%x8h=112%

This means the tank has lost all of its water.

You can also do 500/100=5 <- 1% of the tank, then multiply it by 14 and it gives you 70 litres. Then, multiply this by 8 and its gonna be 560 litres. So this means the tanks is going to have 0 litres left at the end.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
