It's not clear what did you mean with this equation. But I guess you need the balanced net ionic equation, as I've seen that problem before. So here it is: $Mg^{2+} +2OH -\ \textgreater \ Mg(OH)_{2}$

Which system is equivalent to y= 9x^2 x+y=5 ?

melomori [17]

Answer : Option A

Explanation:

we can clearly see that from x+ y=5 we can substitute y = 5-x in y = 9x^2

Option B is clearly incorrect x can not be y -5

Option C is incorrect because y can not be 5 +x

Option D is incorrect because its y = 9x^2 not y^2 =9x^2 so y can not be 3x

if its y^2 = 9x^2 then only implies y = 3x

svlad2 [7]

Answer:

£13.5.

Step-by-step explanation:

Let the share of Brendon, Asha and Julie is 3x, 2x and 6x respectively.

The total amount of money that Asha and Julie recieve is £36

i.e.

2x+6x = 36

8x = 36

x = (36/8)

Amount recieved by Brendon,

$B=3\times \dfrac{36}{8}\\\\=\$13.5$

So, the amount of money that brendon receives is £13.5.
