Step-by-step explanation:
2x-y=6 --------(1)
x+y=6 -------(2)
_____ Adding (1) and (2)
3x = 12
x=4
Substitute x on equation (2)
4+y=6
y=2
Answer:
Mass of the cat = 16800kg
Step-by-step explanation:
The volume of the box = its length * its breath * its height- 4m × 3m × 2m = 24
The standard density of water is 1000 Kg/
By Archimedes principle, the mass of a body floating body is equivalent to the mass of the volume liquid displaced
in this case we have
Mass of water displaced = Density of the water × Volume of the water displaced = 1000 Kg/
× 24
= 24000kg
The mass of the box = Box density × Box volume = 24
× 300kg/
= 7200 kg Hence the mass of water displaced = mass of the foating box + mass of th cat
24000kg = mass of cat +7200kg
mass of cat = 24000kg - 7200kg = 16800kg

Because both lines are parallel, if you add the 5x+5 to the 115 those would equal 180 degrees
so you have 5x+5 + 115 = 180
combine like terms:
5x + 120 = 180
subtract 120 from both sides
5x = 60
x = 60/5
x = 12
