Need help one more time.

Let the length of Pine street be x

The above expression in the picture is written as

21 = 3x

Divide both sides by 3

x = 7mi

Therefore the length of Pine street is 7mi

Hope this helps

7

Step-by-step explanation:

If Maple is 3 times as long as Pine, then to figure how long Pine is you need to divide 21 by 3. This is because if Maple is 3 times longer, then you have to divide by 3 to find out how long Pine is 21÷3=7.

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.

i think that you should ask google for the answer to that problem because if we don't know it google does
