We can write an equation in terms of n, the amount of nickels:
25(3n+3)+10(n+1)+5n=265.
Thus:
90n+85=265
Subtracting 85, we have:
90n=180
Therefore, n=2. As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
Answer:
1) x = 3
y = 42
2) x = 50
y = 70
Step-by-step explanation:
1) 12x + 6 = 14x
6 = 2x
x = 3
14(3) = y
42 = y
2) 2x + 10 + x + 20 = 180
3x + 30 =180
3x= 150
x=50
2(50)+10=110
110-180
y=70
The answer is 33 ...............
