Answer: There are 16 million different phone numbers possible.
First, let's find the number of possible phone numbers without the area code. There are 7 numbers in a phone number. There are 10 digits for each position. However, the first one can't be 1 or 0, so there are only 8 options.
Multiply the possibilities to find the total number.
8 x 10 x 10 x 10 x 10 x 10 x 10 = 8,000,000
Since, there are 2 different area codes, just multiply 8 million by 2 to get 16 million.
Answer:
y = 218
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers present)
27 = (20 + 2y + 25 + y + 30)/27
27 = (3y + 75)/27
3y + 75 = 729
3y = 729 - 75
3y = 654
y = 218
5 inches, 6 inches, and 7 inches does not create one because 5*2 plus 6*2 equal 61 not 49 of 7*
Y=2x-3
When you plug it in
2 times 2 is 4 minus 3 is 1
2 times 3 is 6 minus 3 is 3
2 times 5 is 10 minus 3 is 7
2 times 7 is 14 minus 3 is 11
Just plug in the numbers and you will see that
Y=2x-3 is the correct equation for those functions.
