HELP PLSSSS I DONT UNDERSTAND WALLAH

Harlamova29_29 [7]

Answer:

7.2

Step-by-step explanation:

Distance between (4, 3) and (8, 9):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(8 - 4)^2 + (9 - 3)^2}$

$d = \sqrt{(4)^2 + (6)^2}$

$d = \sqrt{16 + 36}$

$d = \sqrt{52} = 7.2$ (nearest tenth)

asambeis [7]

Answer:

( 7x + 11 )( 7x- 11 )

Step-by-step explanation:

( 7x + 11 )( 7x- 11 )

Because 7*7 is 49

-11*11= -121

7*11=77

-7*11= -77

77-77=0

so the answer is 49x^2-121

inna [77]

Answer:

Money in her purse is Rs. 500.

Step-by-step explanation:

Let the money in her purse = Rs. $x\\$

Let the money in her Money box = Rs. $y$

As per question statement,

Double the money in her purse (i.e. $2 \times x$ ) and add it to the amount in money box, she gets Rs. 1700.

$2x+y=1700$ ........ (1)

Triple the money in her purse (i.e. $3\times x$ ) and add it to amount in money box ( $y$ ), she gets Rs. 2200.

$3x+y=2200$ ....... (2)

To find: Money in her purse = ? i.e. $x=?$

Let us solve for $x$ using the two linear equations.

We can use substitution method here i.e. find value of one variable from one equation and then substitute that value in other equation.

Using equation (1), we get the value of $y$ as follows:

$y=1700-2x$

Now, let us put this value of y in equation (2) to find the value of $x$ :

$3x+1700-2x=2200\\\Rightarrow x+1700 = 2200\\\Rightarrow x=2200-1700\\\Rightarrow x = Rs.\ 500$

Money in her purse is Rs. 500.
