PLSSS HURRY A student translated the phrase below into an algebraic expression, and then evaluated if for y = 24. Is the student's work correct? The difference of a number and 6; evaluate when y = 24:

The expression is y

6

. For y = 24, y

6

= 24

6

= 4.

No, the student wrote a division expression instead of a subtraction expression.

No, the student simplified the fraction incorrectly.

No, the student made an error when substituting.

Yes, the student’s work is correct.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
