<span>Let # of nickels = x
So # of dimes = 2x -12, (12 less than twice the # of nickels)
Also when added their total value is $2.55. To show,
0.05(x) + 0.10(2x - 12) = $2.55 -------------- eqn1
continuing,
0.05x+0.2x-1.2=2.55
0.25x = 3.75
x= 15 ------ This is your # of nickels.
In doubt? well just go back eqn1 & substitute x=15, and you get $2.55
2. Let carol's age = x
So, Rauls'age = 2x+5
Adding the their ages will total to 101 years.</span>
Answer:
![p(4) = 5360](https://tex.z-dn.net/?f=p%284%29%20%3D%205360)
Step-by-step explanation:
Given
![p(c) = 1200c + 2(280)](https://tex.z-dn.net/?f=p%28c%29%20%3D%201200c%20%2B%202%28280%29)
Required
Interpret p(4)
This implies that c = 4
Substitute 4 for c in ![p(c) = 1200c + 2(280)](https://tex.z-dn.net/?f=p%28c%29%20%3D%201200c%20%2B%202%28280%29)
![p(4) = 1200 * 4 + 2(280)](https://tex.z-dn.net/?f=p%284%29%20%3D%201200%20%2A%204%20%2B%202%28280%29)
![p(4) = 1200 * 2 * 280](https://tex.z-dn.net/?f=p%284%29%20%3D%201200%20%2A%202%20%2A%20280)
![p(4) = 1200 * 4 + 560](https://tex.z-dn.net/?f=p%284%29%20%3D%201200%20%2A%204%20%2B%20560)
![p(4) = 4800+ 560](https://tex.z-dn.net/?f=p%284%29%20%3D%204800%2B%20560)
![p(4) = 5360](https://tex.z-dn.net/?f=p%284%29%20%3D%205360)

Answer:
200x43%=86
Step-by-step explanation:
⁻²/₃x + 7 < x - 8
+ ²/₃x + ²/₃x
7 < 1²/₃x - 8
+ 8 + 8
15 < 1²/₃x
1²/₃ 1²/₃
9 < x
x > 9
Solution Set: {x|x > 9}, (9, ∞)
