Answer:
![30-8p](https://tex.z-dn.net/?f=30-8p)
Step-by-step explanation:
Let p represent cost of each drink.
We have been given that the medium pizza costs two times as much as one drink, so the cost of medium pizza would be
.
We are also told that the large pizza costs three times as much as one drink, so the cost of la pizza would be
.
We have been given that Mary wants to buy one large pizza, one medium pizza, and three drinks.
Since the cost of one drink is p, so cost of 3 three drinks would be
.
The total cost of one large pizza, one medium pizza, and three drinks would be ![2p+3p+3p=8p](https://tex.z-dn.net/?f=2p%2B3p%2B3p%3D8p)
Mary started with $30, so amount left after all of her purchases would be 30 minus total cost of all purchases.
![30-8p](https://tex.z-dn.net/?f=30-8p)
Therefore, Mary will have
dollars left after making all of her purchases.
For this case we have that by definition, the density is given by:
![d = \frac {M} {V}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%20%7BM%7D%20%7BV%7D)
Where:
M: It is the mass
V: It is the volume
According to the data of the statement we have:
![V = 24 \ cm ^ 3\\d = 8.7 \frac {g} {cm ^ 3}](https://tex.z-dn.net/?f=V%20%3D%2024%20%5C%20cm%20%5E%203%5C%5Cd%20%3D%208.7%20%5Cfrac%20%7Bg%7D%20%7Bcm%20%5E%203%7D)
So, the mass is given by:
![M = d * V\\M = 24 \ cm ^ 3 * 8.7 \frac {g} {cm ^ 3}\\M = 208.8 \ g](https://tex.z-dn.net/?f=M%20%3D%20d%20%2A%20V%5C%5CM%20%3D%2024%20%5C%20cm%20%5E%203%20%2A%208.7%20%5Cfrac%20%7Bg%7D%20%7Bcm%20%5E%203%7D%5C%5CM%20%3D%20208.8%20%5C%20g)
Thus, the mass of the brass ornament is![208.8 \ g](https://tex.z-dn.net/?f=208.8%20%5C%20g)
Answer:
![208.8 \ g](https://tex.z-dn.net/?f=208.8%20%5C%20g)
Answer:
step-by-step explanation:
Yes, but only if you insist on including addends with a value of 0.
