I would use long division to show my work. But I can tell you the answer. The answer is 121.
Answer:
15400√5−45π
Step-by-step explanation:
Rewrite the expression, pull the terms out from the radical, cancel the common factors, and multiply.
<em>This is a classic algebra problem with 2 equations and 2 unknowns. Let N = #nickles and D=#dimes.
</em>
<em>
</em>
<em>Then N+D=65 the number of coins he has.
</em>
<em>
</em>
<em>Also 5N +10D=490 working the amount of money in pennies. Put equation 1 into 2
.</em>
<em>
</em>
<em>5N+10(65-N)=490
.</em>
<em>
</em>
<em>5N+650-10N=490
.</em>
<em>
</em>
<em>-5N=-160
.</em>
<em>
</em>
<em>N=32 and D=33
</em>
<em>
</em>
<em>To check 32 + 33 = 65
</em>
<em>
</em>
<em>160 + 330 = 490 (in 1c increments)</em>
