Answer:
a.
b. $37.50
Step-by-step explanation:
To find out how much the 5 were paying in total, we can add the bill and the tip. This gives us x + 10. Since there are 5 people and they are splitting the bill equally, the total amount would be divided by 5 to get the amount each person pays: 
. We already know the amount they each paid, as it is given as $9.50. Both expressions represent the same thing, do we can set them equal to each other:
Now, we can solve.
First, we can multiply by 5 on both sides to get:
47.5 = x + 10
And then subtract 10:
x = 37.5
This means the bill before the tip was $37.50
Linear equation with a negative rate of change because the balance would decrease by the same amount each day.
The formula for the volume of a cone is:
To solve, we input your numbers of 1.5 radius and 23 height (radius is diameter divided in half)
Your answer is 162.58
good morning,
Answer:
2,6,18
Step-by-step explanation:
6/2=3 and 18/6=3 then 2,6,18 represent a geometric series.
6/2=3 and 10/6≠3 then 2,6,10 doesn’t represent a Géométric series.

Recall that an implicit function is a relation given by the form:
Where 
is a function of two or more variables. In this case, that function is:
and is implicit because we can define it as:
having two variables.
So, let's take the derivative:
Applying chain rule:
But:
