Given:

A sum of money is divided between A,B and C in the ratio 9:8:7.

Total sum is 480.

To find:

The part of money A get.

Solution:

Let A, B and C get 9x, 8x and 7x respectively.

Total sum is 480.

9x+8x+7x=480

24x=480

Divide both sides by 24.

x=\dfrac{480}{24}

x=20

Now,

A\ get =9x

A\ get =9(20)

A\ get =180

Therefore, amount received by A is 180.

There are 107 coins in a jar, all dimes and nickels. The coins are worth $6.70. How many of each kind of
weqwewe [10]

<em>d</em> = number of dimes

<em>n</em> = number of nickels

The jar contains a total of 107 coins, so

<em>d</em> + <em>n</em> = 107

Each dime is worth $0.10 and each nickel is worth $0.05, and the jar contains a total value of $6.70, so

0.10<em>d</em> + 0.05<em>n</em> = 6.70

Multiply both sides of the second equation by 100 to eliminate the decimal points:

10<em>d</em> + 5<em>n</em> = 670

Multiply both sides of the first equation by -5:

-5<em>d</em> - 5<em>n</em> = -535

Add the corresponding sides of these two equations to eliminate <em>n</em> and solve for <em>d</em> :

(10<em>d</em> + 5<em>n</em>) + (-5<em>d</em> - 5<em>n</em>) = 670 + (-535)

(10 - 5)<em>d</em> + (5 - 5)<em>n</em> = 670 - 535

5<em>d</em> = 135

<em>d</em> = 135/5 = 27

Then

<em>n</em> = 107 - <em>d</em> = 80

so the jar contains 27 dimes and 80 nickels.
