Melanie’s mom is letting her redecorate her room. She has bought scrapbook paper to lay across. Each piece of scrapbook paper is one foot by one foot. She starts by covering one wall. That wall is 11 feet by 10 feet. How many pieces of paper will she need to buy to cover her wall?

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.

is there any answers choices? l can try to you if there is answer choices to this question,so sorry
