Answer 1

Answer: THE ANSWER IS THE FIRST ONE

Step-by-step explanation:

1400/69/999

Answer 2

Simple,

you have ALL the equations set up, just solve for W.

1.)

w+3w=90

4w=90

w=22.5

2.)

w+3w+w+3w=90

8w=90

w=11.25

3.)

2*w+2*3w=90

2w+6w=90

8w=90

w=11.25

4.)

2*(3w+w)=90

6w+2w=90

8w=90

w=11.25

Now, out of ALL those which one was different?

A. (w+3w=90)

This equation did not match with all the others. Thus, your answer. :D
