Answer:
The missing reason is Subtraction Property of Equality.
Step-by-step explanation:
⇒ (Given)
On Solving we get;
Multiplying 2 on both side we get;

⇒ (Multiplication Property of Equality)
Now Subtracting Both side by 10 we get;

⇒ (Subtraction Property of Equality)
Now Dividing both side by 3 we get;

⇒ (Division Property of Equality)
Hence the missing reason is Subtraction Property of Equality.
Factor out 3x
Answer: 3x(x - 5)
There are 6 nickels and 14 pennies.
There are 20 total coins.
The ratio of nickels to coins is 6:20.
Both of these are divisible by 2, so we can reduce this to 3:10.
Mean is the "meanest" because it requires the most work. Add up the values in your data set and divide by the number of terms in the data.
Let x represent attendees at Harry's Hoedown, then
Mean = 
41 = 
123 = 48 + 33 + x
123 = 81 + x
42 = x
Answer: 42
