Juhi sells a washing machine for Rs 13500. She loses 20% in the bargain . What was the price at which she bought it
➽ Let the cost price of the washing machine be a variable and apply the condition that the loss Juhi faced was 20% of the cost price, i.e., Rs. 13,500 is 80% of the cost price to form an equation. Solve the equation to get the answer.
Solution :➽ The selling price of the washing machine after bargain = Rs 13, 500
➽ percentage of loss she had in the bargain = 20 %
let the price paid by juhi be x
➽ Now interpreting the statement in the question
in mathematical form we get :
[tex] \implies[/tex] loss = Rs 2 / 10 × 2
[tex] \implies[/tex] Loss = Rs 2 / 10 × x
➽ According to the simple marketing norm, if we subtract the loss from the buying price, we will be getting the selling price for which Juhi sold the washing machine.
Profit / loss = purchasing price - Selling price
Substituting the values the above equation, we get;
[tex] \implies[/tex] 2 x / 10 = x - 13500
[tex] \implies[/tex] 2 x / 10 = x - 13500 / 2
On cross-multiplication, we get;
2 x = 10 ( x - 13500 )
[tex] \implies[/tex] 2 x = 10 x - 13500
[tex] \implies[/tex] 8 x = 13500
∴ x = 13500 / 8 = 16875
∴ Hence the price that Juhi paid for buying the Washing machine was Rs. 16,875.Additional information :
❑ Don’t get confused and take the 20% of the selling price while you solve, as you should be very clear that the percentage loss or profit are terms related to the actual pricing not to the price for which you crack the deal. The other way of thinking of this is that the selling price might vary from buyer to buyer depending on the bargain they put in, but the percentage should be defined from a fixed mark so that you can easily handle it. The reason that most products in the market have an MRP tag on it making it easier for all the sellers to handle their margins.

How many solutions does this system have?
->
2x-3y = 10
-4x+6y=-20
one
two
an infinite number
no solution
Answer: I think there is only one
Step-by-step explanation:
Answer:
an infinite number
Step-by-step explanation:
Let's solve for y for both equations.
[tex]2x-3y=10\\-3y=10-2x\\y=\frac{2}{3}x-\frac{10}{3}[/tex]
[tex]-4x+6y=-20\\6y=4x-20\\y=\frac{4}{6} x-\frac{20}{6}[/tex]
By reducing fractions we get:
[tex]y=\frac{2}{3}x- \frac{10}{3}[/tex]
These two equations are EXACTLY the same.
Therefore, this system has an infinite number amount of solutions.
Using desmos graphing calculator, you can't see both lines because they're exactly the same line.

does 5+4=8 and does 1+1=2
Answer:
5 + 4 = 8 (False)
1 + 1 = 2 (True)
Step-by-step explanation:
First Case:
5+4=8
No this is not correct as when 5 is added to 4 then the result should be - (1+1+1+1+1) + (1+1+1+1)
= 1 + 1 + 1 + 1 + 1 + 1 + 1 +1 +1
= 9
So this is not correct.
Second Case:
1 + 1 = 2
Yes this is correct when 1 and 1 are added for two times it results in 2.

A college student takes the same number of credits each semester. She had 12 credits when she started, and after 6
semesters, she had 96 credits.
Which of these expresses the rate at which she is earning credits?
Answer:
x = 14
Step-by-step explanation:
Credits = 12 Semesters = 6 Total Credits = 96
6x = 96 - 12
6x = 84
Divide 6x = 84 by 6.
x = 14
[tex]\frac{96 credits-12 credits}{6 semesters} =\frac{84 credits}{6 credits} = \frac{14 credits}{1 semester}[/tex]

We need a rock garden with a perimeter of 12 feet and an area of 8 square feet
Length: Feet
Width: Feet
Answer:
Length: 4 feet
Width: 2 feet
Step-by-step explanation:
The only possibilities that could get an area of 8 feet are 4 x 2 and 8 x 1
However, it has to be 4 x 2 because the 8 x 1 dimension won't have a perimeter of 12 feet.
The dimensions of 4 x 2 will have an area of 8 square feet, since 4(2) = 8
It will also have a perimeter of 12 feet because 4 + 4 + 2 + 2 = 12
So, the length is 4 feet and the width is 2 feet
Jayden has $10 in a savings account. The interest rate is 5%, compounded annually.
To the nearest cent, how much interest will he earn in 2 years?
$
Submit
Answer:
$1
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 10 × 0.05 × 2 = 1
I = $ 1.00
The simple interest accumulated
on a principal of $ 10.00
at a rate of 5% per year
for 2 years is $ 1.00.

dy/dx=2xy/x²+y² solve
Answer:
[tex]y=\frac{-1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}\ or \ \frac{1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}[/tex]
Step-by-step explanation:
As it is first order nonlinear ordinary differential equation
Let y(x) = x v(x)
2xy/(x²+y²)=2v/(v^2+1)
dy=xdv+vdx
dy/dx=d(dv/dx)+v
x(dv/dx)+v=(2v)/(v^2+1)
dv/dx=[(2v)/(v^2+1)-v]/x
[tex]\frac{dv}{dx}=\frac{-(v^2-1)v}{x(v^2+1)}[/tex]
[tex]\frac{v^2+1}{(v^2-1)v}dv=\frac{-1}{x}dx[/tex]
∫[tex]\frac{v^2+1}{(v^2-1)v}dv[/tex] = ∫[tex]\frac{-1}{x}dx[/tex]u=v^2
du=2vdv
Left hand side:
∫[tex]\frac{v^2+1}{v(v^2-1)}dv[/tex]
=∫[tex]\frac{u+1}{2u(u-1)}du[/tex]
=[tex]\frac{1}{2}[/tex]∫[tex](\frac{2}{u-1} -\frac{1}{u} )du[/tex]
=[tex]ln(u-1)-\frac{ln(u)}{2} +c[/tex]
=[tex]ln(v^2-1)-\frac{ln(v^2)}{2}+c[/tex]
Right hand side:
[tex]=-ln(x)[/tex]
Solve for v:
[tex]v=-\frac{-c_{1}+\sqrt{c_{2}+4x^2 } }{2x} \ or \ \frac{-c_{1}+\sqrt{c_{2}+4x^2 } }{2x}\\[/tex]
[tex]y=\frac{-1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}\ or \ \frac{1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}[/tex]

The national weather service reports the daily temperature in degrees
Fahrenheit. The scientific community reports temperature in degrees Celsius.
The formula F = 1.8C + 32 relates Celsius, C, to Fahrenheit F Solve the formula
for C.
Answer:
[tex]C =\frac{5}{9}(F - 32)[/tex]
Step-by-step explanation:
Given
[tex]F = 1.8C + 32[/tex]
Required
Solve for C
[tex]F = 1.8C + 32[/tex]
Subtract 32 from both sides
[tex]F-32 = 1.8C + 32-32[/tex]
[tex]F-32 = 1.8C[/tex]
Divide both sides by 1.8
[tex]\frac{1}{1.8}(F - 32) = C[/tex]
Express the decimal as fraction
[tex]\frac{1}{18/10}(F - 32) = C[/tex]
[tex]\frac{10}{18}(F - 32) = C[/tex]
Simplify
[tex]\frac{5}{9}(F - 32) = C[/tex]
[tex]C =\frac{5}{9}(F - 32)[/tex]

the act, process, or an instance of eliminating or discharging: such as. a : the act of discharging or excreting waste products from the body.
orElimination is the process of getting rid of something, whether it's waste, errors, or the competition. Elimination comes from the Latin word limen, which means threshold.
