2. The length of a football field, including the two end zones, is How long is the football field in feet?
Write the conversion factors that relate yards and feet.
120 yd
360 ft
120 ft
or
40 yd
3. What are the desired units?
What are the original units?
Circle the conversion factor above that has the desired units in the numerator
and the original units in the denominator.

360 ft and question 3 isn’t fully listed

Step-by-step explanation:it’s 100 yards and 10 in each end zone so 120x3=360

i think asking google will you get the answer to that question

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.
