We use the equation 2x+8x=50.

10x=50
x=5

The rectangle will be 20 cm long and 5 cm wide.

Hope this helps!

Answer:

5 cm ( width ) , 20 cm (length)

Step-by-step explanation:

Let width = w

Let length = 4w

Perimeter = 50

Perimeter formula for a rectangle = 2l + 2w

Plug in the variables (width and length)

2(w) + 2(4w) = 50

2w + 8w = 50

10w = 50

w = 5

<u>Remember, recall that length = 4w</u>

length = 4w

length = 4(5)

length = 20

Therefore, the dimensions of the rectangle are 5 by 20 cm

A tennis shop sold twenty $100 racquets at an 8% profit and ten $80 bags at a 15% loss. The profit on the combined transaction w
Sergeeva-Olga [200]
So first let me assume that the Total profit of the racquets are 8 percentage and not individually.

Now to find the profit we can do

20 x 100= 2000

Now
8=x/2000*100
X= 160

And now for loss
10x80=800

Now

15= x/800*100
X=120

Now profit =

160-120 = 40

The profit was only 40
