Answer:

The error in the question is that in the second line, both sides are not multiplied by x. This causes an imbalance in the equation.

Step-by-step explanation:

\frac{5}{x}= x-4

Multiply both sides by x.

x(\frac{5}{x}) = x(x-4)

5= x^{2} -4x

Subtract 5 from the equations.

x^{2} -4x-5=0

Factorise the equation (Quadratics)

(x-5)(x+1)=0

x=5 or x=-1

this is a clear picture from the last one. can u show me the steps of how u worked out the answer plz
azamat

One piece at a time:

4(p+2) means 4 times everything inside the parentheses.
That's 
               4(p)  +  4(2)  =  4p + 8 .

3(2p-3) means 3 times everything inside the parentheses.
That's   
               3(2p)  +  3(-3)  =  6p - 9 .

Now add everything up:

               4p + 8 + 6p - 9 .

Add all the p's together:   4p + 6p = 10p

Add all the plain numbers together:   8 - 9 = -1

The final result is:        10p - 1 .

A campus apartment has two bedrooms and two attached bathrooms and rents for $1,025 per month plus an average of $60 per month f
Zanzabum

I can save $2,128 in my academic year and my roommate can save $392 in their academic year.

Step-by-step explanation:

Total housing amount= rent + electricity= $1,025 + $60= $1,085 per month

My rent is 40% of $1,085 which equals $434 a month while my roommate’s rent would be 60% of $1,085 which equals $651 a month.

The scholarship gives me $700 a month for housing out of which I spend $434 and my roommate spends $651.

I save; $700 - $434 = $266 a month

My roommate saves; $700 - $651 = $49 a month.

An academic year lasts for 8 months so my savings= $266 x 8 = $2,128

My roommate’s savings= $49 x 8 = $392

Using the side-splitter theorem, Daniel wrote a proportion for the segments formed by line segment DE. What is EC?
AfilCa [17]
We manipulate the given equation in order to solve for EC. We do this by cross multiplying. 
The resulting equation will be:
EC = (4 x 3)/5
EC = 12/5 = 2.4

Additionally, the side-splitter theorem works for this problem since DE and AC are parallel to each other, therefore splitting the remaining two sides into proportional segments.
