Can you show me a picture of the problem?
Answer:
10 nickels and 10 quarters
Step-by-step explanation:
Given
Number of coins: 20
Vaiue of coins = $3.00
Required
Number of Nickels and Quarters;
<em>Let N =Nickels and Q =Quarters</em>
The total coins is represented as:

1 nickel is equivalent to $0.05 and 1 quarter is equivalent to $0.25; So

Make N the subject of formula in the first equation

Substitute this in the second equation


Collect like terms


Multiply both sides by 5


Recall that N = 20 - Q


Add them. Pentagram interior angle is 540. 105+101+112+113=431. 540-431=109 Hence, 109 is the answer. Please brainliest.
