Solve the equation : x^(2)+5=3(x^(2)-3)

Fittoniya [83]

Answer:

x = ± 2

Step-by-step explanation:

Given

x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )

0 = 2x² - 8 ( add 8 to both sides )

8 = 2x² ( divide both sides by 2 )

4 = x² ( take the square root of both sides )

x = ± $\sqrt{4}$ = ± 2

How do i solve this rational expression r-4/5r=1/5r+1

NNADVOKAT [17]

r - 4/5r = 1/5r + 1

Subtract 1/5r from each side: r - 4/5r - 1/5r = 1

Combine all the 'r' terms on the left side:

   r - 5/5r = 1

   r - r = 1

   0 = 1

There is no value of 'r' that can make ' 0 = 1 ' a true statement.
So the equation has <em>no solution</em>.

andrezito [222]

Answer:

probability that Marnie and Noomi are both selected=0.1

Step-by-step explanation:

A group of 5 managers (Joon, Kendra, Lee, Marnie and Noomi), 2 people are randomly selected to attend a conference in Las Vegas.

the possibility of selecting 2 from 5 manages is 5C2 ways

$5C2= \frac{5!}{2!(5-2)!} =10$

There is only one choice of selecting Marine and Noomi from 5 managers

So probability of selecting Marine and Noomi is

$\frac{1}{10} =0.1$

1) -53 + 8x = 3x + 47

murzikaleks [220]

Solve for x
-53 + 8x = 3x + 47
8x - 3x = 47 + 53
5x = 100
x = 20
