Answer: $18
Step-by-step explanation:
Let x= Pretax price of the meal.
Given: Sales tax = 8%
Tip percent = 20%
As per given ,
Amount spent = ( Pretax price) + (Sales tax ) of (Pretax price) + (Tip percent)of (Pretax price)
= x+ 8% of x + 20% of x
= x +0.08+0.20x
= 1.28x
∵ Amount spent = $23.04
So,

Hence, the pretax price of the meal= $18.
Answer:
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Step-by-step explanation:
We need to solve the linear system of equations.

We can write second equation y=x-4 as: 
Let:

Now, Adding equation 1 and 2

So, we get x = 1
Now, put value of x in second equation to find value of y:

So, we get y = -3
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Answer:
In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero.

Step-by-step explanation:
If five is a factor, it means that number can be evenly divided by five. Think about it like you're counting by fives or doing the fives times tables.
5, 10, 15, 20, 25, 30, 35, 40, 45, 50 etc.
As you can see, the only numbers that are in the ones place are 5 and 0.
