6x−5y=20
Which procedure will produce a single equation in one variable? Select all the procedures that apply.

A.
Subtract the first equation from the second equation.

B.
Subtract the second equation from the first equation.

C.
Multiply the first equation by 18; multiply the second equation by 18; add the equations.

D.

E.

Multiply the first equation by 3; multiply the second equation by − 2;add the two equations.

Step-by-step explanation:

All of these procedures work because they are canceling out the x and y values in both equations.

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
