4 0

Answer:

Step-by-step explanation:

For a number to be divisible by 12, it has to be divisible by both 3 and 4. This number is divisible by 3 as the sum of its digits is 18, and 18 is divisible by 3. However, 459 is not divisible by 4 as it is an odd number. Because of this, 459 is not divisible by 12.

M is the midpoint of AN, A has coordinates

maksim [4K]

Step-by-step explanation:

According to Question , M is the midpoint of AN, A has coordinates (-7,4), and M has coordinates (-4, -1).

Figure :-

$\setlength{\unitlength}{1 cm}\begin{picture}(20,12) \put(4,0.2){\line(0,-1){0.4}}\put(1,0){\line(1,0){6}} \put(3.8,-0.6){$\bf M(-4,-1) $} \put(1,-0.6){$\bf A (-7,4)$} \put(6.8,-0.6){$\bf N(x,y)$} \end{picture}$

Let the coordinates of N be ( x , y )

Now , according to Midpoint Formula , the midpoint of points say A(x , y) and B (x' , y') is given by ,

$\boxed{\blue{ \bf Midpoint =\bigg( \dfrac{x+x'}{2} , \dfrac{y+y'}{2} \bigg) }}$

On using this formula ,

$=> Midpoint = \bigg( \dfrac{x+x'}{2} , \dfrac{y+y'}{2} \bigg) \\ \\ => (-4, 1) = \bigg( \dfrac{x -7 }{2} , \dfrac{y + 4 }{2}\bigg) \\ \\ => -4 = \dfrac{x-7}{2} \\\\ => x - 7 = -8 \\\\ => x = 7 -8 \\\\ \boxed{\red{\sf=> x = -1 }} \\\\ => \dfrac{y+4}{2}=-1 \\\\=> y +4 = -2 \\ \\ y = -4-2 \\\\\boxed{\red{\sf=> y = -6 }}$

After a 40% discount the cost of a sofa is $471 what was the original cost of the sofa?

sp2606 [1]

100% - 40% = 60%, meaning the discounted price is really just 60% of the original 100% price, let's say the 100% price is hmmmm "x".

if 60% of the original price is $471, what is the 100% or namely "x"?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 471&60\\ x&100 \end{array}\implies \cfrac{471}{x}=\cfrac{60}{100}\implies \cfrac{471}{x}=\cfrac{3}{5}\implies 2355 = 3x \\\\\\ \cfrac{2355}{3}=x\implies 785=x$
