Solve the following pair of linearequations by elimintion method3x+2y-2=0; 2x+ 5y +6=0

Answer»

Step-by-step explanation:

$\sf 3x + 2y - 2 = 0$

$\sf 2x + 5y + <klux>6</klux> = 0$

$\text{Writing the <klux>EQUATIONS</klux> in their standard form,}$

3x + 2y - 2 = 0

3x + 2y = 2

2x + 5y + 6 = 0

2x + 5y = - 6

$\sf 3x + 2y = 2$

$\sf 2x + 5y = -6$

Let's eliminate x .

Multiplying the first eq. by 2 and 2nd eq. by 3 to make the coefficients of x same in both eq.

$\sf 2(3x+2y=2)$

$\sf 3(2x + 5y = -6)$

(Subtracting the equations will CHANGE the signs in each term)

$\sf \: 6x + 4y = 4$

(-) $\sf \underline{6x (-)+ 15y = (-)-18}$

-11y = 22

$\boxed{\sf y = -2}$

$\sf 3x + 2y=2$

$\sf 3x + 2(-2) = 2$

$\sf \implies 3x-4=2$

$\sf \implies 3x = 4+2$

$\sf \implies 3x = 6$

$\boxed{ \sf x=2}$

Hope it helps.

Solve the pair of equations 3/x-1/y=-9 and 2/x+3/y=5

Answer»

Answer

x = - 1/2 , y = 1/3

Given

$\bullet \;\; \tt \dfrac{3}{x}-\dfrac{1}{y}=-9\\\\\bullet \;\; \tt \dfrac{2}{x}+\dfrac{3}{y}=5$

To Find

x and y values

Solution

$\tt \dfrac{3}{x}-\dfrac{1}{y}=-9\\\\\tt \implies \dfrac{9}{x}-\dfrac{3}{y}=-27...(1)[Multiply\ with\ 3]\\\\\tt \dfrac{2}{x}+\dfrac{3}{y}=5...(2)\\\\$

By adding (1) , (2) , we GET ,

$\implies \tt \bigg(\dfrac{9}{x}-\dfrac{3}{y}\bigg)+\bigg(\dfrac{2}{x}+\dfrac{3}{y}\bigg)=-27+5\\\\\implies \tt \dfrac{9}{x}-\cancel{\dfrac{3}{y}}+\dfrac{2}{x}+\cancel{\dfrac{3}{y}}=-22\\\\\implies \tt \dfrac{11}{x}=-22\\\\\implies \tt x=\dfrac{11}{-22}\\\\\implies \tt x=- \dfrac{1}{2}$

SUB. x value in (2) , we get ,

$\implies \tt \dfrac{2}{(-1/2)}+\dfrac{3}{y}=5\\\\\implies \tt -4+\dfrac{3}{y}=5\\\\\implies \tt \dfrac{3}{y}=9\\\\\implies \tt y=\dfrac{3}{9}\\\\\implies \tt y=\dfrac{1}{3}$

t1 ≈ 10 sec

by USING equation of motion, s = ut + (1/2) at²we get

100 = u x 10 + (1/2) a (10)² = 100

100 = u x 10 + (1/2 ) x a x 10 x 10

= 100 = 10{u + (1/2) x a x 10)

= 100/10 = u + 5a

= 10 = u+5 a .........(1)

to find initial velocity for second case we use first equation of motion v = u + at on first motion we get v = u + a x 10 = v = u + 10a

Using second equation of motion s = ut + (1/2) gt² for second motion we get

150 = (u + 10a)x10 + (1/2) a (10)² = 150 = 10X(u + 10a) + (1/2) g x10x10

= 150 = 10 {(u +10a) + (1/2) x 10 x a} = 150/10 = u + 10a + 5a

= 15 = u + 15a= u + 15a = 15 ......(2)

Now subtracting equation (1) from equation (2) we get

u + 15a - (u + 5a) = 15 - 10 = u + 15a - u - 5a = 5

= u - u + 15a - 5a = 5

= 10a = 5 = a = 5/10

= a = 1/2

substituting this value of a in equation (1) we get

u + 5 x (1/2) = 10 = u + (5/2) = 10

= u = 10 - 5/2 = 10 - 2.5

= u = 7.5 m/s

The perimeter of rectangle is 20 cm. If the length of on side of the rectangle is 6 cm, then its breadth will be

Answer»

Given :

PERIMETER of RECTANGLE = 20cm
Length of Rectangle = 6cm

To Find :

Breadth of Rectangle

Solution :

$\longmapsto\tt{Perimeter=20cm}$

$\longmapsto\tt{Length=6cm}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{20=2(6+b)}$

$\longmapsto\tt{\cancel\dfrac{20}{2}=6+b}$

$\longmapsto\tt{10=6+b}$

$\longmapsto\tt{10-6=b}$

$\longmapsto\tt\bold{b=4cm}$

So , The Breadth of Rectangle is 4cm..

━━━━━━━━━━━━━━━━━━━━

VERIFICATION :

$\longmapsto\tt{20=2(6+4)}$

$\longmapsto\tt{20=2(10)}$

$\longmapsto\tt\bold{20=20}$

A quadrilateral of diagolnal is 24 cm and 10 cm . What is the perimeter of quadrilateral

Answer»

Answer:

As the diagonal BISECTED each other then

10÷2=5

24÷2=12

as they bisected at RIGHT angle so we USE Pythagoras theorem

(each SIDE of the quadrilateral)^2=

(5)^2+(12)^2

19000.

LCM and HCF of 21,28,36,45

Answer»

Step-by-step EXPLANATION:

by prime factorization

$$\BEGIN{lgathered}21 = 3 \times 7 \\ 28 = 2 \times 2 \times 7 \\ 36 = 2 \times 2 \times 3 \times 3 \\ 45 = 3 \times 3 \times 5\end{lgathered}$$

now HCF is the common one

therefore hcf = 1 (as there are no common factor )

lcm =

$$\begin{lgathered}2 \times 2 \times 3 \times 3 \times 5 \times 7 \\ = 1260\end{lgathered}$$
