Answer:
The cost of 2 quintal of rice is $10,000.
Step-by-step explanation:
To determine the cost of 2 quintals of rice, knowing that 90 kilos of said product is worth $ 4,500, it is first necessary to establish the equivalence between quintals and kilograms. In this regard, a quintal is equivalent to 100 kilograms, so 2 quintals are equivalent to 200 kilos.
Now, to determine the cost per kilogram of rice, the following calculation is required:
4,500 / 90 = X
50 = X
Therefore, 1 kilogram of rice costs $ 50. Thus, since 200 x 50 equals 10,000, 2 quintals of rice will cost $ 10,000.
So we're looking at two rectangles, one cut out of the other, so all you do is find the area of the big one, base times height equals area, minus the area of the small one, base times height equals area. So the equation you have to solve for is this,
Area=(12.6X14)-(3X8.4)
Only 3 is needed

It would be around 6 months to accumulate $1000 in your account
Answer:
The equation of the line that is parallel to given line and passes through the point (-8, -3) is: ![y = 5x+37](https://tex.z-dn.net/?f=y%20%3D%205x%2B37)
Step-by-step explanation:
Given equation of line is:
![y=5x-3](https://tex.z-dn.net/?f=y%3D5x-3)
The general form of equation of line in slope-intercept form is written as:
![y = mx+b](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb)
Here m(co-efficient of x) is the slope of the line and b is the y-intercept.
Comparing the given equation with the general form we get
m = 5
Two parallel lines have same slope so the slope of any line parallel to given line will also be 5.
Let m1 be the slope of required line parallel to y=5x-3
Then m1=5
Putting in general form
![y = m_1x+b](https://tex.z-dn.net/?f=y%20%3D%20m_1x%2Bb)
![y=5x+b](https://tex.z-dn.net/?f=y%3D5x%2Bb)
To find the value of b(y-intercept) the given point has to be put in the equation from which the line passes.
The point is (-8,-3)
![-3 = 5(-8)+b\\-3 = -40+b\\b = -3+40\\b = 37](https://tex.z-dn.net/?f=-3%20%3D%205%28-8%29%2Bb%5C%5C-3%20%3D%20-40%2Bb%5C%5Cb%20%3D%20-3%2B40%5C%5Cb%20%3D%2037)
Putting the value of b and m1, we get
![y = 5x+37](https://tex.z-dn.net/?f=y%20%3D%205x%2B37)
Hence,
The equation of the line that is parallel to given line and passes through the point (-8, -3) is: ![y = 5x+37](https://tex.z-dn.net/?f=y%20%3D%205x%2B37)
