To only make 1/3 of the recipe you would divide all ingredients by 3 or multiply by 1/3, same thing.
Convert 2 1/4 to single fraction first
9/4 * 1/3 = 9/12 = 3/4 cup sugar
I think its d, because A and Cs angles make 180. And B has two equal sides that make it possible to make a triangle. Sorry i couldnt be more helpful
Subtract 4/7 on both sides to get b=-4/7-3. Then simplify.
45+ 35+20=100
R=100=45
N =128
Answer:
Step-by-step explanation:
let y=f(x)
y=10x-10
flip x and y
x=10y-10
10 y=x+10
![y=\frac{1}{10}x+1\\f^{-1}(x)=\frac{1}{10}x+1\\(fof^{-1}{x})=f(f^{-1}(x))=f(\frac{1}{10} x+1)=10(\frac{1}{10} x+1)-10=x+10-10=x\\(fof^{-1})(-10)=-10](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B10%7Dx%2B1%5C%5Cf%5E%7B-1%7D%28x%29%3D%5Cfrac%7B1%7D%7B10%7Dx%2B1%5C%5C%28fof%5E%7B-1%7D%7Bx%7D%29%3Df%28f%5E%7B-1%7D%28x%29%29%3Df%28%5Cfrac%7B1%7D%7B10%7D%20x%2B1%29%3D10%28%5Cfrac%7B1%7D%7B10%7D%20x%2B1%29-10%3Dx%2B10-10%3Dx%5C%5C%28fof%5E%7B-1%7D%29%28-10%29%3D-10)
