Answer:  x = - 2√5, √5/3

Step-by-step explantion

3 √ 5 x 2 + 25 x − 10 √ 5 = 0 35x2+25x−105=0

⇒ 3√5x2 + 30x – 5x – 10√5 = 0  

⇒ 3√5x(x + 2√5) – 5(x + 2√5) = 0  

⇒ (x + 2√5)(3√5x – 5) = 0

x = - 2√5, √5/3

3 \sqrt{5}  {x}^{2} +  25x - 10 \sqrt{5}  = 0 \\  \\ 3 \sqrt{5} {x}^{2}   + 30x - 5x - 10 \sqrt{5}  = 0 \\  \\ 3x( \sqrt{5} x + 10) -  \sqrt{5} ( \sqrt{5}  + 10) = 0 \\  \\ ( \sqrt{5} x + 10)(3x -  \sqrt{5} ) = 0

\sqrt{5} x  + 10 = 0 \\  \\  \sqrt{5}x =  - 10 \\  \\ x =   \frac{ - 10}{ \sqrt{5} }   \\  \\ x =  \frac{ - 2 \times \sqrt{5 }  \times  \sqrt{5} }{ \sqrt{5} }  \\  \\ x = -  2 \sqrt{5} .

3x -  \sqrt{5}  = 0 \\  \\ 3x =  \sqrt{5}  \\  \\ x =  \frac{ \sqrt{5} }{3} .

The values of x are -2√5 & √5/3 .

The quotient of n and 12 subtracted from 100?
Korvikt [17]

Answer:

100 - 12/n

Step-by-step explanation:

quotient means division so

12/n

and subtracted from means say x - 12/n so

100 - 12/n

If you're looking to evaluate it then it would be

4(25n - 3) / n

Out of 32 students in a class, 5 said they ride their bikes to school. based on these results,how many of 800 students in the sc
Colt1911 [192]
Do a proportion.
5/32= x/800
Cross multiply and divide
800 x 5= 4,000
4,000 divided by 32= 125
So answer is 125 students

den301095 [7]

3x - 2y = 8 +

===》 46x = 16

43x + 2y = 8

x = 16/46

x = 8/23

______________________________

3x - 2y = 8

3(8/23) - 2y = 8

24/23 - 2y = 8

2y = 24/23 - 8

y = 12/23 - 4

y = 12/23 - 92/23

y = - 80/23

Which statement is modeled by the expression?
Afina-wow [57]
A librarian has 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.

Example : lets say there are 10 shelves.....so k = 10
150/10 = 15 books on each shelf.
