Balvina knows that 6 cups of rice will make enough spanish rice to feed 15 people. She needs to know how many cups of rice are needed to feed 135 people

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

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

So, 6 is equivalent to 15.

Thus, is equivalent to 135.

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

By cross multiplying we get:

Dividing both sides by 15 we get:

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

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
