An electric utility company determines the monthly bill for a residential customer by adding an energy charge of 7.32 cents per
Sedaia [141]

Answer:

y(x) = 0.0732x + 17.32

Step-by-step explanation:

The equation for the monthly charge has the following format

y(x) = ax + b

In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.

Base charge of $17.32 per month.

This means that b = 17.32

charge of 7.32 cents per kilowatt-hour

Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is a = 0.0732

Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.

y(x) = ax + b

y(x) = 0.0732x + 17.32

How to add fractions? with unlike denominators
stellarik [79]

Answer:

The recipe calls for 19/12 or 1 7/9 cups.


Step-by-step:

In order to get this answer, we have to add all three fractions together. First, we have to find the LCM (Least Common Multiple) between the three denominators:

2: 2, 4, 6, 8, 10, 12

3: 3,6,9,12

4: 4,8,12

The LCM between these three denominators is 12.

4x3=12

2x6=12

3x4=12

You now multiply the numerator by the same number you multiplied by for the denominator in order to get 12:

3/4 becomes 9/12

1/2 becomes 6/12

1/3 becomes 4/12

We now add all the fractions together:

9/12+6/12+4/12= 19/12

We got 19/12 but the answer is an improper fraction so we turn it into a mixed number:

12x1=12 (7 remaining)

This is written as 1 7/12.

Hope this helps! :)
