Answer:

-\frac{3}{20}

Step-by-step explanation:

<u>GIVEN :-</u>

  • One of the two rational numbers = -\frac{9}{20}  

<u>TO FIND :-</u>

  • Sum of two rational numbers = -\frac{3}{5}

<u>SOLUTION :-</u>

Let the another rational number be 'x'.

According to the question , the equation formed will look like this :-

x + (-\frac{9}{20} ) = -\frac{3}{5}

=> x - \frac{9}{20} = -\frac{3}{5}

Now solve the equation.

  • Add  \frac{9}{20} to both the sides of equation in order to isolate 'x'.

=> x - \frac{9}{20} + \frac{9}{20} = -\frac{3}{5} + \frac{9}{20}

=> x = \frac{9}{20} - \frac{3}{5}  = \frac{9 - (3 \times 4)}{20} = \frac{9 -  12}{20} = \frac{-3}{20}

Answer:

-3/20

Step-by-step explanation:

Let other number = x

∴ -9/20 + x = -3/5

∴ x = -3/5 + 9/20

∴ x = -3/20

Hope this helps  :) !!!!

Answer:

The number of children that attended the game was 365

Step-by-step explanation:

Let

x ----> the number of children that attended the game

y ---> the number of adults that attended the game

we know that

x+y=587 ----> equation A

5x+7y=3,379 ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (365,222)

see the attached figure

therefore

The number of children that attended the game was 365
