Step-by-step explanation:

width = x

length= 3x

Area = length * width

3÷243 =3x^2÷3

√81=√x^2

x=9

3x=3*9=27

Width=9

Length=27

goldenfox [79]

Answer:

  0.40x

Step-by-step explanation:

If x is the original price, 60% of x is 0.60x. When that is subtracted from the original price, the sale price is ...

  sale price = x - 0.60x = (1 -0.60)x

  sale price = 0.40x

_____

Full price is 100% of x. If the price has been reduced 60%, then 40% of the original price remains as the sale price.

kramer

Answer:

The first question:

x = -1

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -x - 1  =   -1 • (x + 1)

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

2.1      Solve  :    -x-1 = 0

Add  1  to both sides of the equation :

                     -x = 1

Multiply both sides of the equation by (-1) :  x = -1

One solution was found :

                  x = -1

Hamid published a book of poems. He sold 35 copies in the first week for $10 per copy. He wanted to increase the price of
Natalija [7]

After reading through the story problem, I ended up with this equation:

(35-2)(x+.5) =?

or

(35-2)(10+.5)=?

Explanation:

He sells 35 books for usual weeks. Since he is selling his books at $.50 more his average number of copies decreased by 2.

35-2 = 33

Next, we know that he adds $.50 for his price for each copy. If the price is $10 per copy than it looks like this:

$10+$.50= 10+.5

or if the price is not $10 it will be

$x+$.5= x+.5
