Arecipe for cookies asks for 2/3cup of sugar for ever 2teaspoons of vanilla. how much sugar was used per teaspoon. a. 1/3 b. 1 1/3 c. 2 2/3 d. 3

one and one third, or B

Step-by-step explanation:

you would do 2/3 divided by 2 to find the unit rate. it comes out to be 1.3333  convert into a fraction and the answer is B.

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
