D

Step-by-step explanation:

The perimeter of a rectangle is given by the formula:

From our figure, our length is (2s-5) and our width is (4s-13). So, let's substitute (2s-5) for l and (4s-13) for w. This yields:

We also know that the perimeter is 108. So, substitute that for P:

Solve for s. We can first divide everything by 2:

Combine like terms:

Add or subtract:

Add 18 to both sides:

Divide both sides by 6:

So, the value of s is 12.

Now, substitute this back in to find our length and width:

Substitute 12 for s:

Multiply and subtract:

Now, let's find the width:

Substitute 12 for s:

Multiply and subtract:

So, our length is 19 and our width is 35.

The choice that reflects this is D.

And we're done!

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.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
