The number 350 is separated into three parts (numbers). Dividing the first number by the third will give 2 and dividing the second number by the pfirst number will give 5 and a remainder of 25. Find the three numbers.

Andy has 145 coins in his coin bank. THe number of 5-denomination coins is 10 more than twice the number of 10-denomination coins. The difference between the number of 1-denomination coins and 5-denomination coins is 5 more than the number of 10-denomination coins. How many of each kind of coin does he have?

let the three numbers be a , b , and and c

a+b+c=350

a/c = 2 ---> a = 2c or c = a/2

so a + b + a/2 = 350
3a + 2b = 700

b/a = 5 + 25/a
b= 5a + 25

in 3a + 2b=700
3a + 10a + 50 = 700
13a = 650
a = 50
b = 275
c = 25


check:
50+275+35 = 350 , check!
50/25 = 2 , check
275/50 = 5.5 = 5 + 25/50 = 5 + remainder of 25 , check

Let's solve each problem step by step:

1. The number 350 is separated into three parts (numbers). Dividing the first number by the third will give 2, and dividing the second number by the first number will give 5 and a remainder of 25. Find the three numbers.

Let's assume the three numbers are A, B, and C.

Based on the given information, we can write the following equations:

Equation 1: A/C = 2
Equation 2: B/A = 5 + (25/A)

To solve the problem, we need to find the values of A, B, and C that satisfy both equations simultaneously.

To solve Equation 1, we can multiply both sides by C: A = 2C.

Substituting this value of A into Equation 2, we get: B/(2C) = 5 + (25/(2C))

To simplify this equation, we can multiply both sides by 2C: B = 10C + 25

Now we have a system of two equations:
A = 2C
B = 10C + 25

As we can see, we have two equations and three variables. We need one more equation to solve the problem.

Is there any additional information provided that could help us find the remaining equation?

2. Andy has 145 coins in his coin bank. The number of 5-denomination coins is 10 more than twice the number of 10-denomination coins. The difference between the number of 1-denomination coins and 5-denomination coins is 5 more than the number of 10-denomination coins. How many of each kind of coin does he have?

Let's assume the number of 10-denomination coins is x, the number of 5-denomination coins is y, and the number of 1-denomination coins is z.

Based on the given information, we can write the following equations:

Equation 1: x + y + z = 145 (total number of coins is 145)
Equation 2: y = 2x + 10 (number of 5-denomination coins is 10 more than twice the number of 10-denomination coins)
Equation 3: z - y = x + 5 (the difference between the number of 1-denomination and 5-denomination coins is 5 more than the number of 10-denomination coins)

We now have a system of three equations:
x + y + z = 145
y = 2x + 10
z - y = x + 5

To solve this system of equations, we can use methods like substitution or elimination. By substituting Equation 2 and Equation 3 into Equation 1, we can find the values of x, y, and z that satisfy all three equations.
