Sol = Let the unknown number be, x
         Thus according to the question, {tex}\huge { x+\frac{15}{32} = -\frac{7}{11} }{/tex}
         So, {tex}\huge { x=-\frac{15}{32} -\frac{7}{11} }{/tex}
       => {tex}\huge { x=\frac{(-15\times 11)-(7\times32)}{32\times 11} }{/tex}
       => {tex}\huge { x=\frac{(-165)-(224)}{352} }{/tex}
      => {tex}\huge { x=\frac{-389}{352} }{/tex}
Please write the grammar of the question properly.
It should be like this:
What number should be added to 15 upon 32 to get minus 7 upon 11 ?

2x-y=9........ (i)
3x+y=0 ........ (ii)

add (i) and (ii), we get

5x = 9

x = 9/5

Put x = 9/5 in (ii) , we get
3(9/5) + y = 0

27/5 + y = 0

y = -27/5

(4a+3b)2 - (4a-3b)2 + 48ab

= (4a)2 + (3b)2 + 2(4a)(3b) + (4a)2 + (3b)2 - 2(4a)(3b)+ 48ab

= 16a2 + 9b2 + 24ab + 16a2 + 9b2 - 24ab + 48ab

= 16a2 + 16a2 + 9b2 + 9b2 + 48ab

= 32a2 + 18b2 + 48 ab

X=33 y=10

Parth Rungta 4 years, 7 months ago

Let the two no.s be x and y Then Acc. to the question, x+y=43 - eq. 1 And then Let the larger be x Acc. to the question 2x-3y=36 - eq. 2 Multiplying both the sides of eq. 1 by - 3, we get - 3x+3y= 129 3x+3y= 129 2x-3y=36 5x=165 x = 33 x+y = 43 33+y=43 y= 43 - 33 y= 10 Therefore, x = 33 y = 10

Q. {tex}\LARGE { \frac{5}{4}}{/tex} times a number is 10 more than the number. Find the number?
Sol. =

Covert the statement step by step into a mathematical expression.
=>           Let the unknown number be, x
=>           {tex}\LARGE { \frac{5}{4}}{/tex} times a number = {tex}\LARGE { \frac{5}{4}\times x}{/tex}

=>           10 more than the number = {tex}\LARGE {10 + x}{/tex}   
=>    Therefore, {tex}\LARGE { \frac{5}{4}\times x}{/tex}{tex}\LARGE { = 10 + x}{/tex}


  {tex}\huge {=> 5\times x = 4\times (10+x)}\\ \huge{=> 5 x= 40+4x }\\ \huge{=> 5 x-4x= 40 }\\ \huge{=> x= 40 }\\{/tex}
Final answer, x = 40.

The greatest 5-digit number is 99999 and 
The smallest 5-digit number is 10000.
But by using different digits,

The greatest 5-digit number is 98765 and using 4 at the tenth place we will get
=> 98746
Similarly, The smallest 5-digit number is 10234 and using 4 at the tenth place we will get
=> 10243

So, according to the conditions given in the question:

The greatest 5-digit number is 98746 and 
The smallest 5-digit number is 10243, having 4 at the tenth place and with different digits.

It is a question of construction.
You should use scale, rounder (compass)and pencil to construct it.
Sol: First write all the sides or angles given (if any)
     Name of quadrilateral  = ABCD 
     Sides: AB=4cm
                AC=6cm
                CD=5.4cm
                DA=5.4cm
First make a rough sketch to have an idea of the required sketch.

Using construction steps of 45degree you an make it.
and if you are allowed to use the protractor then only you can make 40 degree with it.

A mistake in the question, "class assado" = cast's a shadow.

Sol:

From eq. 1 and eq. 2 we will get:

{tex}\huge {=>\ \frac{6}{y+3} = \frac{1.5}{3} }\\ \huge {=>\ 6\times3 = 1.5\times(y+3) }\\ \huge {=>\ \frac{18}{1.5} = y+3}\\ \huge {=>\ 12 = \frac{y}{3} }\\ \huge {=>\ 12-3 = y }\\ \huge {=>\ y=9 }\\{/tex}

Thus, the lady is 9 meters away from the lamp post.
All the best :-)...
