Answer:
There is no x value, as there is no solution
Step-by-step explanation:
we have
2x+y=1
Isolate the variable y
y=-2x+1 -----> equation A
4x+2y=-1 ---> equation B
Solve the system of equations by substitution
Substitute the equation A in the equation B and solve for x
4x+2(-2x+1)=-1
4x-4x+2=-1
2=-1 ------> is not true
therefore
The system has no solution
Equation A and equation B are parallel lines with different y-intercepts
Answer:
Answer:
AB = 20 metres
BC = 60 metres
Step-by-step explanation:
Answer:
1344 ft^2
Step-by-step explanation:
From the picture we can see that 4w = 3l, which means that l = (4/3)w. Since w = 12 ft, l = (4/3)(12 ft) = 16 ft. Then the total area of the floor is
(length of floor)(width of floor) = (48 ft)(12 ft + 16 ft) = 1344 ft^2
Given:
There are given the edge of the cube-shaped aquarium has 3 feet.
Explanation:
To find the value, we need to use the volume of the cube formula:
So,
From the formula of volume:

Where
a represents the value of edge.
So,
Put the value of edge into the above formula:
Then,

Now,
The water has a density of 62 pounds per cube foot.
According to the question:
If the weight of 1 cubic foot of water is 62 pounds, then the weight of 27 cube feet water is:

Final answer:
Hence, the water weight of the full aquarium is 1674 pounds, and the table only susupports00 pounds. So the table cannot hold the aquarium.
And,
No, the density of water would not change.
