2l3x+7l-9=25 divide each side by 2l3x+7l-9=12.5 add each side by 9l3x+7l=21.5 since its absolute value there's two cases:3x+7=21.5 solve for x: subtract 7 from both sides and divide by 3x=4.833and 3x+7=-21.5 solve for x: subtract 7 from both sides and divide by 3 againx=-9.5so x=4.833 or -9.5
Assuming that you have more than one of each size jug (you need at least two of one size and one of the other), fill the 7L jug, then pour the water from the 7L jug into the 5L jug. There is now 2L left in the 7L jug. Get a different 7L jug and fill it, then pour that into another 5L jug (or empty the first 5L jug and reuse it). Once again, you will have 2L left over in the 7L jug. Pour that 2L into the other jug with 2L left over and you will have 4 Liters of water.Expressed mathematically, (7 - 5) + (7 - 5) = 4
To determine how many 35ml "nips" are in a 70cl bottle, you first need to convert the volume to the same unit of measurement. There are 1000ml in 1 liter, so a 70cl bottle is equivalent to 700ml. Then, you divide the total volume of the bottle (700ml) by the volume of each "nip" (35ml) to find the answer. In this case, 700ml divided by 35ml equals 20 nips in a 70cl bottle.
