Hello There!
<u><em>n - d = 0</em></u>
<u><em>5n+10d = 90</em></u>
<u><em>----------------------</em></u>
<u><em>n-d = 0</em></u>
<u><em>n+2d = 18</em></u>
<u><em>-------------------</em></u>
<u><em>Subtract and solve for "d":</em></u>
<u><em>3d = 18</em></u>
<u><em>d = 6 (# of dimes)</em></u>
<u><em>n = d = 6 (# of nickels)</em></u>
Answer:
C.
Step-by-step explanation:
Answer:
Both are rational.
Step-by-step explanation:
As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.
And we know the product of two integers is an integer
p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.
Thus a+b and a-b is rational.
Sammy calculated the total amount that he deposited by <em>adding up the total amount deposited in each account.</em>
- The Checking account is used to pay for fixed and variable essential expenses. In this account, Sammy deposited $1,712.
- The Cash account is used for non-essential expenses, like snacks, etc. A total of $260 was deposited into this account.
- The Emergency Savings account is used for both other predictable and unpredictable expenses. A total of $340 was deposited into the account.
- For the Vacation Savings account, it is used to carter for other long-term expenses. A total of $50 was deposited into the account.
- When these accounts are added up, the total deposit made by Sammy can be calculated to be $2,362 ($1,712 + $260 + $340 + $50).
