Does a straw have two holes or one? ​

Water flows at a steady rate from a tap. its takes 40 seconds to fill a 4 litre watering can from the tap. the rate at which water flows from the tap is halved. complete: 4 litres into cm3

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
