Answer:
of cream will remain in the container.
Step-by-step explanation:
Given:
Amount of cream in the container = 
Amount of cream used to make crème brûlée = 
We need to find the amount of cream remain in the container.
Solution:
Now we can say that;
the amount of cream remain in the container is equal to Amount of cream in the container minus Amount of cream used to make crème brûlée.
framing in equation form we get;
amount of cream remain in the container = 
Now we will make the denominator common using LCM we get;
amount of cream remain in the container = 
Now denominators are common so we will solve the numerators.
amount of cream remain in the container = 
Hence
of cream will remain in the container.
Plug each x-value into the equation to get the y-value:

(2,-1)

(0,-2)
Answer:
m∠E= 37°
m∠F=37°
Step-by-step explanation:
Total angle value: 180°
180-106=74
The lengths are the same, so we can determine that the angles E and F are the same. So we divide 74 by 2
74/2= 37
m∠E= 37°
m∠F=37°
Hope this helps! Have a nice day :)
