A farmer buys a tractor for rs.70000 and after using it for some time, he sells it at a loss of 5% to another farmer. He also se

Vedmedyk [2.9K]

Total loss %=10+5=15%

CP=70000
loss%=15%

Now

Loss:-

$\\ \sf\longmapsto 15\%\:of\:70000$

$\\ \sf\longmapsto \dfrac{15}{100}(70000)$

$\\ \sf\longmapsto 10500$

Again

$\\ \sf\longmapsto SP=CP-Loss$

$\\ \sf\longmapsto SP=70000-10500$

$\\ \sf\longmapsto SP=59500$

Third farmer will pay 59500

Which of the following equations has the same solutions as the equations 3x+2y=-12

Marianna [84]

B, C, E, F

<h2>Explanation:</h2>

In this problem, we have the following equation of a line written in Standard form:

$3x+2y=-12$

So we need to choose the equations that has the same solutions as this equation. If we multiply each equation by a constant term and find the same solution as the given equation, then they will have the same solution. This is only true fro options B, C, E and F.

Option B.

$-3x-2y= 12 \\ \\ Multiply \ both \ sides \ by \ -1: \\ \\ (-1)(-3x-2y)=(-1)(12) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option D.

$15x+10y= -60 \\ \\ Multiply \ both \ sides \ by \ 1/5: \\ \\ (\frac{1}{5})(15x+10y)=(\frac{1}{5})(-60) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option E.

$6x+2y= -12 \\ \\ Multiply \ both \ sides \ by \ 1/2: \\ \\ (\frac{1}{2})(6x+2y)=(\frac{1}{2})(-24) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

Option F.

$1.5x+y= -6 \\ \\ Multiply \ both \ sides \ by \ 2: \\ \\ (2)(1.5x+y)=(2)(-6) \\ \\ 3x+2y=-12$

So we get the same given equation. This option is valid!

For the other options, there is no any constant term that multiplies both sides of the equation and gives us the same given equation.

The length of bills backyard swimming pool is 60 feet longer than the width of the pool. The surface area of the water is 1600 s

shutvik [7]

Answer:

The width is 20 ft and the length is 80 ft

Step-by-step explanation:

Area = l * w

l = w +60

SA = 1600 ft^2 ( which is the regular area) The surface area of the water is just what is on top which is length times width

1600 = l*w

Substitute in l = w+60

1600 = (w+60) *w

Distribute the w

1600 = w^2 +60w

Subtract 1600 from each side

1600-1600 = w^2 + 60w -1600

0 = w^2 + 60w -1600

Factor

0=(w-20) (w+80)

Using the zero product property

w-20=0 w+80 =0

w=20 or w=-80

The width cannot be negative so

w=20

Now we need to find the length

l = w+60

l = 60+20

l =80
