Answer:
The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds
Step-by-step explanation:
Let
x ----> amount of 65 cents per pound flour to use
y----> amount of 95 cents per pound flour to use
we know that
---->
----> equation A
----> equation B
substitute equation A in equation B
![0.65x+0.95(100-x)=0.83(100)](https://tex.z-dn.net/?f=0.65x%2B0.95%28100-x%29%3D0.83%28100%29)
Solve for x
![0.65x+95-0.95x=83](https://tex.z-dn.net/?f=0.65x%2B95-0.95x%3D83)
![0.95-0.65x=95-83](https://tex.z-dn.net/?f=0.95-0.65x%3D95-83)
![0.30x=12](https://tex.z-dn.net/?f=0.30x%3D12)
![x=40\ lb](https://tex.z-dn.net/?f=x%3D40%5C%20lb)
Find the value of y
![y=100-40=60\ lb](https://tex.z-dn.net/?f=y%3D100-40%3D60%5C%20lb)
therefore
The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds
Answer:
(in step-by-step explanation)
Step-by-step explanation:
The ratio x:y is the same as the fraction x/y if that helps, so it is basically putting the coordinates into a fraction. Here is a video that might help also: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-ratios-prop-topic/cc-6th-ratio-word-problems/v/ratios-on-coordinate-plane
Coordinate planes are a way of expressing data, so if it makes it easier, put the data into a ratio! Sorry, it is a bit difficult to explain such a broad question.
In order to solve these you first need a ratio.
From what we can tell, the ration from LEFT to RIGHT is:
2:3
Therefore, in order to have a 2:3 ratio, we need 5 parts total (2 parts on left + 3 parts on right = 5 total parts!)
A) 60
B) 90
The answer is A because the closed circles mean that it is a possibility for x and the line means it can be anywhere in between.
Hope this helps!
Simplify the expression
6² + 9²
6² = 6 x 6 = 36
9² = 9 x 9 = 81
36 + 81 = 117
117 is a rational number ∴ <span>6</span>²<span> plus 9</span>² is rational
hope this helps
