Answer:
well let’s break this down
Let’s make type a coffee “a”
And type b coffee “b”
a is 4.35
b is 5.70
We knwo that b is twice as many as a
The total is 614.25
So we can do soemthing like this
4.35a+ (5.70b)2 = 614.25
Now solve
If we simplify its really
4.35a+11.40b =614.25
I like multiply by a 100 to get rid of decimals
435a+1140b=61425
Here we can go 2 ways
We can isoalte a or b
im gonna isloate b
so it would be (61425-435a)/1140 =b
Now we can use that as a subsitube to find a
Now we can just do this
435a +1140(61425-435a)/1140 = 61425
Pop it through an algebra calculator (just search up math pa..Pa and copy paste it, edit if needed) and then you’d get your answer
to inverse a equation make all y's x and andy x's y
Thus the inverse is
x=4y-8
Evaluated to
4y=x+8
y= \frac{1}{4}x +2
(x+y=31)2
2x-y=11
2x+2y=62
- 2x -y=11
3y=51
y=17
x+17=31
x=14
y-x=3
38 es par 35 es par eso es todo?
Answer:
806 yd sq.
Step-by-step explanation:
Area=(length)(width), so to find the surface area you can just find the area of each side and then add then all together.
They already gave you the length of some of the sides, so you should use that to help you find the length of all the sides.
You can see the entire prism's length is 17 yd, width is 4 yd, and height is 14 yd.
The large visible side's area would be (14)(17)= 283 yd. There's another one of these side's on the other side that we can't see. So we would do (283)(2) = 566 yd sq.
Next, we'll find the area of the side on the side by doing (14)(4)=56. Once again, there's two of these sides so we do (56)(2) to get 112 yd sq for this side.
Finally, we'll find the area of the top side. We can do (4)(17) =68, and then (68)(2) to get 138 yd sq.
Now, we have the area of each side of the prism! To find the total surface area, just add them all together. 556+112+138=806.
The surface area would be 806 yd sq.
