Answer:
2.75
Step-by-step explanation:
55-11(4)=2.75
2.75+11=13.75
13.75x4=55
Answer:
175 hope this helps
Step-by-step explanation:
Add 72 and 113
then subtract that from 360
Answer:
9 people
Step-by-step explanation:
Start by writing an equation.
The total bill is 134.03. The bill is totally paid by Marcus and the other guests. This will go on the other side of the equation.
Since we don't know how many guests there were, we can use variable x to represent the value that we're trying to find.
So here is our equation.
134.04 = 20.45 + 12.62x
Now, just solve for x, or isolate x.
Subtract 20.45 from both sides.
134.04 - 20.45 = 12.62x
Divide both sides by 12.62.
113.59/12.62 = x
Simplify.
x = 9
Since x is 9, we know that there were 9 other people at the dinner party.
Answer:
Part A) see the explanation
Part B) 
Step-by-step explanation:
Part A)
we know that
A relationship between two variables, x, and C, represent a proportional variation if it can be expressed in the form
or 
Let
C ---> is the total cost (represent the output or dependent variable)
x ----> is the number of books (represent the input or independent variable)
In this problem
we have a proportional relationship between the variables x and C
Part B) we know that
The linear equation is given by

The constant of proportionality k is the same that the slope or unit rate of the linear equation
In this problem the constant k is given

so

For x=12 books
substitute in the equation and solve for C

In function notation
