Little Melinda has nickels and quarters in her bank. She has nine fewer nickels than quarters. She has $4.65 in the bank. How ma

erastovalidia [21]

Answer:

Step-by-step explanation:

n=q-9

5n+25q=465, using n from above this becomes

5(q-9)+25q=465

5q-45+25q=465

30q-45=465

30q=510

q=17, and since n=q-9

n=17-9

n=8

So Melinda has 8 nickels and 17 quarters.

Keeping in mind that i² = -1,

$\bf \begin{array}{c|ccccc}
-1+i&&1&5&1&4\\
&&&-1+i\\ &&---&--&--&--\\
&&1&4+i
\end{array}\\\\
-------------------------------\\\\
(-1+i)(4+i)\implies -4-i+4i+\stackrel{-1}{i^2}\implies -4-i+4i-1
\\\\\\
-5+3i\\\\
-------------------------------$

$\bf \begin{array}{c|ccccc}
-1+i&&1&5&1&4\\
&&&-1+i&-5+3i\\
&&---&---&----&--\\
&&1&4+i&-4+3i
\end{array}\\\\
-------------------------------\\\\
(-1+i)(-4+3i)\implies 4-3i-4i+3\stackrel{-1}{i^2}\implies 4-3i-4i-3
\\\\\\
1-7i\\\\
-------------------------------\\\\
\begin{array}{c|cccccc}
-1+i&&1&5&1&4\\
&&&-1+i&-5+3i&1-7i\\
&&---&---&----&---\\
&&1&4+i&-4+3i&\boxed{5-7i}&\leftarrow remainder
\end{array}$

recall that a factor of the expression, gives a remainder of 0, and this one doesn't.
