2. You like 3 teaspoons of sugar and 1/4 cup of milk in each cup of coffee (3/4 cup coffee, 1/4 cup milk) you drink. Before leaving for a trip you prepare a thermos that holds 2 quarts of liquid. What quantities of coffee, sugar and milk will you use? (Assume the sugar occupies no volume.)​

the answer is b

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

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.
