There are 84 blue marbles and 204 red marbles. We want to place these marbles in some boxes so that there is the same number of red marbles in each box and
the same number of blue marbles in each of the boxes. How many boxes do we
need?

i think the answer is b.

step-by-step explanation:

not 100% sure though.

the answer is a beach is the best place to be

need more info

step-by-step explanation:

what do you mean by "representation"? graph? table? etc.

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.
