Answer:
82
Step-by-step explanation:
let X = the number of hamburgers sold
let Y = the number of cheeseburgers sold a combined total of 328 were sold
so: X + Y = 328
cheeseburgers = 3 times the number of hamburgers sold
so: Y = 3X
substitute 3X into the equation for Y
X + 3X = 328
4X = 328
divide both sides by 4 to get the variable X by itself
X = 82
so: 82 hamburgers were sold Friday
i think it would be y=3/5

Answer:
The final step in determining the volume of the pyramid is V = one-third (30) (12).
Step-by-step explanation:
Given : Abdul started solving for the volume of the pyramid using the steps below. V = one-third B h
A rectangular pyramid with a base of 10 meters by 3 meters and a height of 12 meters.
To find : What is the final step in determining the volume of the pyramid?
Solution :
The volume of pyramid is V = one-third B h
The base is B=(3) (10) = 30 meters squared
The height is h=12 meters
Substitute the value,
V = one-third (30) (12)
Therefore, the final step in determining the volume of the pyramid is V = one-third (30) (12).
So, option 1 is correct.
