A recipe for brownies calls for 4 cups of flour to 6 cups of sugar how many cups of sugar per cup of flour does the recipe requi
Andrews [41]

So, we have 4 cups of flour and 6 cups of sugar and we need to know how many cups of sugar per cup of flour does the recipe require. Because it is requested to know how many cups of sugar per cup of flour does the recipe require, we need to divide the amount of flour and sugar by the amount of flour, and we will know what we need to know.

4 cups of flour / 4 = 1 cup flour

6 cups of sugar / 4 = 6/4 = 3/2 = 1 1/2 cups of sugar per cup of flour is the solution

What is the slope of the line that passes through the pair of points?<br> (-2,7), (18, 1)
Oliga [24]

Answer:

Your slope of the line is -3/10.

Step-by-step explanation:

Use the following equation:

<em>m</em> (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-2 , 7)

(x₂ , y₂) = (18 , 1)

Plug in the corresponding numbers to the corresponding variables:

<em>m</em> = (1 - 7)/(18 - (-2))

Simplify. First solve the parenthesis, then divide:

<em>m</em> = (-6)/(18 + 2)

<em>m</em> = -6/20

Simplify.

<em>m</em> = (-6/20)/(2/2) = -3/10

Your slope of the line is -3/10.
