Chapter 7 of the Jiuzhang suanshu presents a problem of two linear equations involving acres of land and their respective prices. One of the two equations can be translated to:
300x + 300 x plus StartFraction 500 over 7 EndFraction left-parenthesis 87.5 right-parenthesis equals 10,000.y = 10000
If y = 87.5, what is the value for x?
The required value of x is 12.5 when y = 87.5
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
300x + 500/7y = 10,000
Now for the value of x put the value of y which is 87.5 in the given equation we get,
300x + 500/(7*87.5) = 10,000
Solving we get,
300x + 500/612.5 = 10,000
Simplifying the fraction we get,
300x + 43,750/7 = 10,000
Dividing the fraction we get
300x + 6,250 = 10,000
Subtract 6,250 from both sides
300x + 6,250 - 6,250 = 10,000 - 6,250
Solving we get,
300x = 3,750
Divide both sides by 300
x = 3,750/300
Solving we get
x = 12.5
this is the required value of x when y = 87.5
Thus, the required value of x is 12.5 when y= 87.5

How to write the inequality?Here we have the mathematical sentence:
"The sum of a number v and 6.2 is at least -4.7"
The sum is written as:
6.2 + v
And that is equal to or more than -4.7, then we need to use the symbol ≥, with that, we can write the inequality:

What are line integrals?Line integrals are integrals evaluated along a curve. It is given by I = ∫F.dr
where dr = dxi + dyj
How to find the given integral ∫F.dr?Given that F = <7xy, 2y²> is a vector field in the plane, and C the path y = 8x² joining (0,0) to (1,8) in the plane.
So, we need to find the line integral ∫F.dr
Since
F = <7xy, 2y²> = (7xy)i + (2y²)j and dr = dxi + dyjSo, ∫F.dr = ∫[(7xy)i + (2y²)j.(dxi + dyj)] = ∫(7xydx + 2y²dy)
We integrate y from 0 to 8 and x from 0 to 1 and susbstitute y = 8x² into the equation. So, we have
∫F.dr = ∫(7xydx + ∫2y²dy)
= ∫(7x(8x²)dx + ∫2y²dy)
= ∫56x³dx + ∫2y²dy
= 56∫₀¹x³dx + 2∫₀⁸y²dy
= 56[x⁴/4]₀¹ + 2[y³/3]₀⁸
= 56[1⁴/4 - 0⁴/4] + 2[8³/3 - 0³/3]
= 56[1/4 - 0] + 2[512/3 - 0]
= 56[1/4} + 2[512/3]
= 14 + 1024/3
= (42 + 1024)/3
= 1066/3
= 355¹/₃ units
So, given that F = <7xy, 2y²> is a vector field in the plane, and C the path y = 8x² joining (0,0) to (1,8) in the plane.the line integral ∫F.dr = 355¹/₃ units

The volume of a cone varies jointly as its height, and the square of its radius. If a cone with a height of 8 cm and a radius of 2 cm has a volume of 33.5 cm3 what is the volume of a cone with a height of 6 cm and a radius of 4 cm?
The volume of a cone with a height of 6 cm and a radius of 4 cm is:
V = 100.5 cm³
What is the volume of a cone with a height of 6cm and a radius of 4cm?
If the volume of a cone varies jointly as its height, and the square of its radius, then we can write the equation:
V = R²*H*k
Where:
R = radius
H = height
k = constant of the variation.
Here we know that if R = 2cm and H = 8cm, the volume is 33.5 cm³, then we can replace that to get:
33.5 cm³ = (2cm)²*8cm*k
The value of k is:
(33.5 cm³)/( (2cm)²*8cm ) = k = 1.046875
Then the formula for the volume is:
V = R²*H*1.046875
Now if the radius is 4cm and the height is 6cm, the volume will be:
V = (4cm)²*(6cm)*1.046875 = 100.5 cm³

Say you are given the graph of the line y x. Write the equation of the line that is perpendicular to the given line and goes through the point (8, 2).
The equation of a line perpendicular to y = x that passes through the point (8,2) is y = -x + 10
How to find the equation of the perpendicular line?The equation of the line is given as
y = x
Rewrite the equation as
y = x
A linear equation is represented as
y = mx + c
Where
Slope = m
So, we have
m = 1
The slopes of perpendicular lines are opposite reciprocals
This means that
m2 = -1/m1
So, we have
m = -1/1
Evaluate
m = -1
The equation of the perpendicular line is then calculated as
y = m(x - x1) + y1
Where
(x1, y1) = (8, 2)
This gives
y = -1(x - 8) + 2
Evaluate
y = -x + 8 + 2
Evaluate the sum and the difference
y = -x + 10
So, the equation of a line perpendicular to y = x that passes through the point (8,2) is y = -x + 10

Indiras spring garden has half as many tulips as daffodils and three times as many hyacinths as tulips. If there are a total of 204 flowers in indiras garden, how many of each flower does she have ?
Indira is having 34 tulips, 68 daffodils and 102 hyacinths , altogether 204 flowers in her spring garden.
Given, In Indira's springtime garden, there are three times more hyacinths than tulips and half as many daffodils as tulips.
let the number of tulips be = x
the number of daffodils be = y
the number of hyacinths be = z
hence according to the question,
tulips are (x) = 1/2 (y) = y/2
hyacinths are (z) = 3(x) = 3x
therefore, total flowers = 204
tulips ₊ daffodils ₊ hyacinths = 204
y/2 ₊ y ₊ 3x = 204
substitute x value in the above equation.
y/2 ₊ y ₊ 3(y/2) = 204
take LCM
y ₊ 2y ₊ 3y = 408
6y = 408
y = 408/6
y = 68
hence the number of daffodils is 68.
now substitute y value in x = y/2
x = 68/2
x = 34
now substitute x value in z= 3x
z = 3(34)
z = 102
hence we get the number of tulips,daffodils and hyacinths as 34 , 68 and 102 respectively.

The perimeter of a rectangle is 320 feet. Find the length and width if the length is an odd integer and the width is 5 times the next consecutive odd integer
The length of rectangle is 25 feet and the width of rectangle is 135 feet.
How can the perimeter be calculated?The perimeter of a rectangle can be calculated by making use of the formular that will be written below which is
P = 2(l + b)
But if we are to interpret the question, then we will have
2(L + W) = 320 after the simplification
and from the above simplification , we will have
L+ W=160
But according to the question, Odd integers that follow each other with a difference of 2, hence we will have x as the odd integer, then go in a consecutive odd integers manner we will have
W = 5(x+2)
Then if we substitute, we have
[x+5x+10=160]
Then simplify we have
6x=150
x=25
Then input x into the width equation, then, width will be 135 feet.
Therefore, The length of rectangle is 25 feet and the width of rectangle is 135 feet.
