Sol = Let the unknown number be, x
Thus according to the question, $\huge { x+\frac{15}{32} = -\frac{7}{11} }$
So, $\huge { x=-\frac{15}{32} -\frac{7}{11} }$
=> $\huge { x=\frac{(-15\times 11)-(7\times32)}{32\times 11} }$
=> $\huge { x=\frac{(-165)-(224)}{352} }$
=> $\huge { x=\frac{-389}{352} }$
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

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. $\LARGE { \frac{5}{4}}$ 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
=> $\LARGE { \frac{5}{4}}$ times a number = $\LARGE { \frac{5}{4}\times x}$

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

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

Rajan Kumar Pasi 4 years, 10 months ago

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.

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

Sol:

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

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