Think About the Process Ajar contains only pennies, nickels, dimes, and quarters. There are 22 pennies, 23 dimes, and 16 quarters. The rest of the coins are nickels. There are 82 coins in all. How
many of the coins are not nickels? If n represents the number of nickels in the jar, what equation
could you use to find n?

61 coins that are not nickels

n = 82 - 61

Step-by-step explanation:

22 pennies + 23 dimes + 16 quarters = 61 coins that are not nickels

n = no. of nickels

n = 82 - 61

center= (-2,0)

radius= sqrt2/2

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.
