In the attachment

Step-by-step explanation:

$-4(1-x)\leq-12+2x\qquad\text{use distributive property}\\\\(-4)(1)+(-4)(-x)\leq-12+2x\\\\-4+4x\leq-12+2x\qquad\text{add 4 to both sides}\\\\4x\leq-8+2x\qquad\text{subtract 2x from both sides}\\\\2x\leq-8\qquad\text{divide both sides by 2}\\\\x\leq-4$

A vessel full of water weighs 16.5kg. when the vessel is half full, it weighs 10.5kg. find the weight of the empty vessel

omeli [17]

We know that
A vessel full of water weighs 16.5kg
when the vessel is half full, it weights 10.5kg
so
16.5 kg-10.5 kg=6 kg is the weight of half water
the weight of full water=6kg*2------> 12 kg
so
the weight of the vessel=A vessel full of water-the weight of a full water
the weight of the vessel=16.5 kg-12kg=4.5 kg

the answer is
the weight of the vessel is 4.5 kg
