Let n = the number of nickels that Ari has.
Let p = the number of pennies that Ari has.
The total number of coins she has is 22.
n + p = 22
We have our first equation... But we another one to solve this.
Each penny is going to be $0.01 and a nickel is work $0.05.
And the total is $0.54
Our second equation. 0.05n + 0.01p = 0.54
n + p = 22
0.05n + 0.01p = 0.54
Multiply the top by -0.05
-0.05n - 0.05p = -1.1
0.05n + 0.01p = 0.54
The n terms cancel out.
-0.04p = -0.56
p = 14
Substitute p back into the top equation.
n + 14 = 22
n = 8
So, Ari has 8 nickels and 14 pennies.

Answer:
-1
Step-by-step explanation:
You can find the average my finding the sum of all temperatures and then dividing it by the number of temperatures ( in this case 7)
So you get (-3-5+3+7-2-2-5)/7=-7/7=-1
If the angle is 45° then the sides are equal. Both x and y is 14 sqrt(2)
