Answer:
39 pounds of type A coffee were used.
Step-by-step explanation:
Given: Cost of type A coffee is $4.15 per pound and cost of type B coffee is $5.25 per pound. Also, blend used four times as many pounds of type B coffee as type A.
To find: How many pounds of type A coffee were used.
Let
be the number of pounds of type A coffee and
be the number of pounds of type B coffee.
Then, according to question,
and ![y=4x](https://tex.z-dn.net/?f=y%3D4x)
Substituting
in
, we get
![4.15x+5.25(4x)=980.85](https://tex.z-dn.net/?f=4.15x%2B5.25%284x%29%3D980.85)
⇒![4.15x+21x=980.85](https://tex.z-dn.net/?f=4.15x%2B21x%3D980.85)
⇒![25.15x=980.85](https://tex.z-dn.net/?f=25.15x%3D980.85)
⇒![x=\frac{980.85}{25.15}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B980.85%7D%7B25.15%7D)
⇒![x=39](https://tex.z-dn.net/?f=x%3D39)
Therefore, 39 pounds of type A coffee were used.
Answer:
-5/2
Step-by-step explanation:
Perpendicular slope is always the negative reciprical. This basically means the opposite sign and the nubers are flipped.
To find the equation of the line that passes through the given points, you first must find the slope using the slope intercept formula (y2-y1)/(x2-x1) which is used by plugging your coordinate values into the formula. This would look like this:
(5-1)/(3-1)
When simplified, you should get 4/2 or (when simplified) 2 as your slope.
Now that you have this, you can plug in one of your coordinates and your slope into y=mx+b to solve for b. Since I am using the coordinate (1,1), the equation would look like this: 1=2(1)+b
When solved for b, you should get b=-1
Finally, now that you have the b and m (slope) values, you can write your equation as y=2x-1

RO = OW = 5.1
BRW + ORW = BRO = OWB
57 + 42 = 99 = OWB
I'm not entirely sure if these are correct, if its not, then im sorry.
