Step-by-step explanation:
1st digit is 1 number (1)
2nd digit is (3,4,5) so it's 3 numbers
third digit is (6,7,8,9) is it's 4 numbers
last 7 digits is 10 (0,1,2,3,4,5,6,7,8,9)
multiply
1*3*4*10=120
so answer is 120 phone numbers
Answer:
Read my explanation
Step-by-step explanation:
Since they both end with a 0, you can just cancel it out. So you'd have 484/9.
The answer to that is 53.7777777777...
So the decimal would come before the 3 and after the 7.
I hope this helped and have a good rest of your day!
Answer:
5y + 4 and 7y + 4 - 2y
Step-by-step explanation:
Look at the second choice:-
5y + 4 and 7y + 4 - 2y
Simplifying the second expression:-
7y + 4 - 2y
= 5y + 4
So both expressions are equivalent . Therefore if you plug in 2 or 5 the results will be the same.
To complete the square, you would add to both sides (8/2)^2 = (4)^2 = 16. So, the correct answer would be D.
