x+y=12000
y=12000-x
(x)(.0615)+y(.06)=12736
x(.0615)+(12000-x)(.06)=12736
Let me know if you need more help. This is a system of equations problem I believe.

+ 474 equals
483.
First, multiply 3 two (3x3) times to get 9. Your problem should look like: 9 + 474.
Second, add 9 + 474 to get 483, which is the correct answer.
Answer: 2.625
Explanation: 5 1/4 - 2 5/8 = 21/8 = 2 5/8 = 2.625
I believe the answer is 11
Step-by-step explanation:
We have,
The frequency of note A is 880 Hz and the frequency of note D is 1175 Hz. It is required to find the ratio of D to A.
It means
.
Using the values of frequency of D and A. So,

In decimal form,

In integer form,
