Ezra counts the number of passengers who are already on the bus when he gets on each morning. His data for the last 15 days are

Answer:

Step-by-step explanation:

The equation provided is:

d = 5x + 10xf

We need to isolate x from this equation.

Factoring out x from the right side gives us,

d=x(5+10f)

To find x, divide both sides by (5+10f),

Thus, this represents the sought value for x.

For Chris, the calculation for his monthly telephone expense is as follows:

Where "x" denotes each minute used.

Given that Chris can afford a bill of $86, we have:

The total minutes of usage must not exceed 500 per month. Consequently, the viable choice is option C.

Answer:

Option C

Answer:

The price per kilogram of salami amounts to = $9.1

Step-by-step explanation:

Given:

Hailey spent $13 on kg of sliced salami.

We need to determine the cost per kg of the salami.

Solution:

We will use the unitary method to find the cost for one kilogram of salami.

If kg of salami costs $13

Then the cost for 1 kg of salami in dollars =

When dividing mixed numbers, we convert them to fractions.

⇒

⇒

To divide fractions, we take the reciprocal of the divisor and multiply.

⇒

⇒

⇒

⇒

Hence, the cost per kilogram of salami is = $9.1

Answer:

The charge for the first three hours is $4 per hour.

Subsequently, the rate decreases to $2 per hour until the sixth hour.

Between the sixth and tenth hours, the cost is reduced further to $1 per hour.

The maximum charge for renting the bike is $30.

Step-by-step explanation:

The incline on the graph indicates the hourly rate for the bike rental.

During the initial three hours, the rental fee rises by $4 for each hour.

From the third to the sixth hour, the graph’s slope indicates a rate of $2 per hour for the rental.

The charge drops to $1 per hour from the sixth to the tenth hour.

After the tenth hour, the price, P, remains constant. The highest fee for the bike rental is $30.

Jason can confirm the accuracy of his solution by substituting the calculated x value back into the original equation to check if it holds true. If the equality fails, it indicates that his calculated x is incorrect.
