Step-by-step explanation:
18 minutes in total.
4 1/2 minutes per pot.
so, all we need to do is find out how often 4 1/2 fits into 18. that is what division is for.
18 / (4 1/2)
4 1/2 = 2×4/2 + 1/2 = 8/2 + 1/2 = 9/2
18 / 9/2 = 18/1 / 9/2 = 2×18 / 9×1 = 36/9 = 4
there are 4 coffee pots.
The correct option for this question would be 50 degrees
Answer:
-9/91
Step-by-step explanation:
-9/91
![f(x) = 2x + 3](https://tex.z-dn.net/?f=f%28x%29%20%3D%202x%20%2B%203)
![y = 2x + 3](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%203)
Subtract the sides of the equation minus 3
![y - 3 = 2x](https://tex.z-dn.net/?f=y%20-%203%20%3D%202x)
Divided the sides of the equation by 2
![\frac{y - 3}{2} = x \\](https://tex.z-dn.net/?f=%20%5Cfrac%7By%20-%203%7D%7B2%7D%20%3D%20x%20%5C%5C%20%20)
So ;
![{f}^{ - 1}(x) = \frac{x - 3}{2} \\](https://tex.z-dn.net/?f=%20%20%7Bf%7D%5E%7B%20-%201%7D%28x%29%20%3D%20%20%5Cfrac%7Bx%20-%203%7D%7B2%7D%20%5C%5C%20%20%20)
