Answer:

n = 55

Step-by-step explanation:

Let's do it  in the form of an equation.

(n + 6) / (n - 5) = 1,25

(n - 5) x 1,25 = n + 6

(n - 5 + 5) x 1,25 = n + 6 + 5 (I added 5 in both sides to make it equal.)

n x 1,25 = n + 11

(n - 11) x 1,25 = n + 11 -11

(n - 11) x 1,25 = n

1,25n - 13,75 = n

n + 13,75 = 1,25n

n + 13,75 - 1,25n = 1,25n - 1,25n (I substracted 1,25n from both sides.)

-0,25n + 13,75 = 0

-0,25xn + 13,75 - 13,75 = 0 - 13,75 (Now I substracted 13,75 from both sides.)

-0,25n = - 13,75

n = -13,75 : - 0,25

n = 55

It may look a little long, but this is the way I solved it.

if i helped you, please do me the Brainliest. :)

AleksandrR [38]

Answer:

R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]

Step-by-step explanation:

Squaring both sides of equation:

     I^2 = (ER)^2/(R^2 + (WL)^2)

<=>(ER)^2 = (I^2)*(R^2 + (WL)^2)

<=>(ER)^2 - (IR)^2 = (IWL)^2

<=> R^2(E^2 - I^2) = (IWL)^2

<=> R^2 = (IWL)^2/(E^2 - I^2)

<=> R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]

Hope this helps!

The diagonal of a rectangle is 25 in. The width is 15 in. What is the area of the rectangle
djyliett [7]
Here is your answer > >

Width of rectangle =15 inches

Length of rectangle =?

Diagonal of rectangle = 25 inches

We know that

(Diagonal of rectagle)^2=length^2+breadth^2

(25)^2=l^2+(15)^2

625=l^2+225

l^2=625-225

l^2=400

l=Root 400

l=20 inches

Hope it helps!

Thankyou ☆ ☆
