To determine if an ordered pair is a solution to a system of linear equations in two variables, a. substitute the coordinates of the ordered pair into either equation to see if it produces a true statement b. substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each c. substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement d. substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement

B

Step-by-step explanation:

When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
