The first digit can only range from 1-9, resulting in 9 possible options. The next four digits can range from 0-9, resulting in 10 options for each. Since the last two digits remain the same, they do not affect the sample size. Using the fundamental counting principle, we can find the amount of telephone numbers possible in the following equation.
Answer:
x = 4
Step-by-step explanation:
4x+2=18
subtract 2 to both sides
2 cancels out
4x=16
divide both by 4
4 cancels out
x= 4

Answer:
The required inequality that shows the maximum number of packages is
.
Step-by-step explanation:
Consider the provided information.
Each package weighs 3 pounds and Jacob weighs 99 pounds.
let <em>n</em> is the maximum number of package that Jacob can carry with himself in the elevator.
Thus, the total weight of Jacob while having <em>n</em> packages on the elevator is:

The elevator can carry a maximum of 300 pounds at a time, therefore.

Now, subtract 99 from both sides and divide the obtained inequality with 3.




Thus, the Jacob can carry maximum 67 packages.
Hence, the required inequality that shows the maximum number of packages is
.
