Answer 17

from what i read ...

Jack's pet dog has been prescribed
x mg of a medicine per day.

Each pill of the medicine has 15 mg of the medicine.

Jack has to give his dog a total of 25 pills.
If Jack gave his dog medicine for 7 days: 25/7 pills a day

Answer 18

the expression given seems to be:
\[25-7(\frac x{15})\]

Part A: What does x over 15 represent? (3 points)

Part B: What does the second term of the expression represent? (3 points)

Part C: What does the entire expression represent? (4 points)

Answer 19

right

Answer 20

thanks for transcribing amistre. I'm just gonna do my part:
x was the amount to give in a day.
15 mg was one pill.

so what does the term in brackets state

Answer 21

so then part a would be the about of pills to give the dog per day?

Answer 22

x is the amount to give out entotal over the course of 7 days according to the expression

Answer 23

1/15th of the total medicine per day, right?

Answer 24

right, so then for part A I would put something like "the variable x/15 represents how many pills to give the dog per day"?

Answer 25

yes

Answer 26

im prolly misreading this

Answer 27

x is daily dosage

Answer 28

so then when it goes to part B, what would the second term be? cause I thought x/15 was the second term

Answer 29

hello?

Answer 30

I also thought so

in fact 7 times x/15 is the 2nd

Answer 31

so then the second term would represent the total amount of pills for the week?

Answer 32

ye

Answer 33

then what about part 3?

Answer 34

stabar..why don't you try doing your own work..this isn't for a quiz this is for a quiz from FLVS!! this is academic Integrity

Answer 35

This is what I submitted for those who'd like to see all the answers in one reply:
I'll reply with what I scored after it's graded.

Part A: x/15 represents the amount of milligrams prescribed divided by the amount of milligrams in one pill of the medicine.

Part B: 7x represents the amount of milligrams prescribed times the number of days the dog will be taking the medicine. After you were to find the value of x and multiply the two factors, you need to divide the product by 15 because 15 milligrams is the amount of medicine in one pill.

Part C: First let's break the expression down and analyze each part:

25: This represents the total amount of pills that were given to Jack for his pet dog.
7: This is the number of days that the dog will be taking the medicine.
15: This is the total amount of milligrams of medicine in one pill.
x: The total amount of milligrams of medicine in 25 pills.

Now that we've observed each term in the expression we can piece them together.

25 (pills) - 7 (days) * x (amount of milligrams of medicine in 25 pills) ÷ 15 (amount of milligrams of medicine in one pill)

So, after you find the quotient of 7x and 15, you'll have the total amount of milligrams of medicine that the dog has not taken over the course of 7 days. 25 (pills) minus y (amount of left over milligrams of medicine) equals the amount of pills not taken.

So, the expression 25 - 7x/15 represents the amount of pills the dog has not consumed/taken.
