The two equations given in the question are
x = y + 10
And
x = 2y + 3
Now let us substitute the value of x in the second equation with that of the first equation. We get
x = 2y + 3
y + 10 = 2y + 3
y - 2y = 3 - 10
- y = - 7
y = 7
Now putting the value of y in the first equation, we get
x = y + 10
= 7 + 10
= 17
So the value of x comes out to be 17 and the value of y comes out to be 7.
Determine the quadrant adding or subtracting periods -10pi/3+2pi=-4pi/3+2pi=2pi/3
which is the second quadrant because
first quadrant is between 0 and pi/2
second quadrant is between pi/2 and pi
third quadrant is between pi and 3pi/2
fourth is between 3pi/2 and 2pi
now we find the terminal angle since it is the second quadrant we use theta'=pi-theta=pi-2pi/3=pi/3
sin(pi/3)=sqrt(3)/2 sin is positive in the second quadrant
cos(pi/3)=-0.5 cos is negative in the second quadrant
tan(pi/3)=sin(pi/3)/cos(pi/3)=-sqrt(3) tan is negative in the second quadrant

Answer:
1/3 to 1/2 teaspoons of lemon extract
Step-by-step explanation:
The proportions you say are ...
1 tsp lemon extract : 2 tbsp lemon juice
extract : juice = 1 tsp : 6 tsp = 1 : 6
If you have 2-3 teaspoons of lemon juice, you have the equivalent of 2/6 to 3/6 = 1/3 to 1/2 teaspoons of lemon extract.
