Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the House blend

TiliK225 [7]

The ratio House blend/Organic Free Trade blend is the same and must remain the same.

So, the proportion is:

$\frac{140}{168}=\frac{130}{x}$

Where x is the unknown amount of the Organic Free Trade blend.

So, from the proportion, we have:

$\begin{gathered} 140\cdot x=168\cdot130 \\ 140x=21840 \\ \frac{140x}{140}=\frac{21840}{140} \\ x=156 \end{gathered}$

Answer: 156 pounds of Organic Free Trade blend

The midpoint of a sègment is (6,-4) and one endpoint is (13,-2). Find the coordinates of the other endpoint.

gizmo_the_mogwai [7]

let other one be (x,y)

We know midpoint formula

$\boxed{\sf (x,y)=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}$

$\\ \sf\longmapsto (6,-4)=\left(\dfrac{13+x}{2},\dfrac{-2+y}{2}\right)$

$\\ \sf\longmapsto \dfrac{13+x}{2}=6$

$\\ \sf\longmapsto 13+x=12$

$\\ \sf\longmapsto x=12-13$

$\\ \sf\longmapsto x=-1$

And

$\\ \sf\longmapsto \dfrac{-2+y}{2}=-4$

$\\ \sf\longmapsto -2+y=-8$

$\\ \sf\longmapsto y=-8+2$

$\\ \sf\longmapsto y=-6$
