Answer:


Step-by-step explanation:
Let's call x the length of each piece in yards
If the ribbon is cut into 8 equal pieces then the sum of the pieces is:

Then:

Now we solve the equation for x

Divide both sides of equality by 8


So the length of each piece is
of a yard.
This is: 1.125 yards
For 121212 guests we need 555 liters,for 363636 guests how many liters
Guests Soda
121212 555
363636 x
So 121212*x=363636*555
x=363636*555/121212
x=555*3
x=1665
Answer:
x = 3, v = -8
Step-by-step explanation:
Substitute x.

[5 •
= -73 - 11v]
Isolate v.
5
= -73 - 11v
v = -8
Substitute v.
x = 
x = 3
