First you would distribute the 2 to the -8 (because of the parenthithese), which would give you -16.
Then you would add the -3 .
So, your answer would be -19. Hope this helps!

Answer:

54 cups of rice are needed to feed 135 people.

Step-by-step explanation:

Given:

Balvina knows that 6 cups of rice will make enough spanish rice to feed 15 people.

Now, to find the cups of rice needed to feed 135 people.

Let the cups of rice needed to feed 135 people be $x.$

As, 6 cups of rice is needed to feed 15 people.

So, 6 is equivalent to 15.

Thus, $x$ is equivalent to 135.

Now, to get the cups of rice needed to feed 135 people we use cross multiplication method:

$\frac{6}{15} =\frac{x}{135}$

By cross multiplying we get:

$810=15x$

Dividing both sides by 15 we get:

$54=x\\\\x=54\ cups.$

Therefore, 54 cups of rice are needed to feed 135 people.
