Answers
Answer:
The highest common factor of 30 and 45 is 15.
Step-by-step explanation:
factors of 30 = 1, 2, 3, 4, 5, 6, 10, 15, 30 ; factors of 45 are = 1, 3, 5, 9, 15, 45)
Greatest common factor is 15
Answer:
15.
Step-by-step explanation:
HCF is also called GCD. So, you divide both numbers with a common number that can divide both numbers at the same time without a remainder.
3 30 45
5 10 15

The required inequality for the least amount of money he needs to deposit to avoid a fee is 727.29 - 248.50 + x ≥ 500 and he needs to deposit at least $21.21 in her account to avoid a fee.
What is inequality?
A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.
Now it is given that,
Amount in the account = $727.29
Amount in the check = $248.50
Amount need to maintain = $500
Now let x be the Tony needs to deposit.
So, total balance in the account = 727.29 - 248.50 + x
Since, he must maintain a $500 balance to avoid a fee. That means the balance can be greater than or equal to $500.
Thus the required inequality is:
727.29 - 248.50 + x ≥ 500
Adding alike terms,
468.79 + x ≥ 500
Subtracting 468,79 both the side we get,
x ≥ 500 - 468.79
Solving we get,
x ≥ 21.21
Therefore, he needs to deposit at least $21.21 in her account to avoid a fee.
Thus,the required inequality for the least amount of money he needs to deposit to avoid a fee is 727.29 - 248.50 + x ≥ 500 and he needs to deposit at least $21.21 in her account to avoid a fee.

727.29-248.50+x>500
x=how much she needs to deposit
478.79+x>500
subtract 478.79 from both sides
x>21.21
at least $21.21

One landscaper charges $20 for 5 hours of work.
One landscaper’s hourly rate is $15 lower than the other landscaper’s.
Both landscapers charge the same hourly rate and the same fee per job.
Both landscapers charge the same hourly rate, but not the same fee per job.
Answers
What Casey can conclude is D. Both landscapers charge the same hourly rate, but not the same fee per job.
What Casey can conclude based on the given scenario
Both landscapers will charge the same hourly rate because we were told they each charges an hourly rate including a fee for each job.
Their fees per job cannot be the same because Casey substituted an expression for one variable while he solved for the other.
Therefore the correct option is D.
