Answer:
subtraction property of equality
Step-by-step explanation:
The substraction property of equality is the property that states that you can solve the value of an equality by subtracting the value that is adding up to the variable by substracting it from the other side of the equality, an example would be like this:

By substracting form both sides the value that is along the "x" you get the value of the "x".
Answer:
Step-by-step explanation:
let f(x)=ab^x
when x=1,f(x)=6
6=ab
when x=2,f(x)=18
18=ab^2
divide

I believe the answer will be D.
Answer: 16 pieces.
Step-by-step explanation:
Suppose that we have a set with N numbers
{x₁, x₂, x₃, ..., xₙ}
The mean of this set is calculated as:
M = (x₁ + x₂ + x₃ + ... + xₙ)/N
In this case, our set is:
{14, 12, 22, 8, 24}
So we have N = 5.
The mean of this set will be:
M = (14 + 12 + 22 + 8 + 24)/5 = 16
The average/mean number of pieces of sushi he got on each trip is 16 pieces.
