Answer:
let cost of washer be x
cost of dryer be $745-x
we have
cost of washer =$95+($745-x)
x=$95+$745-x
x+x=$840
2x=$840
x=$840/2=$420

Hello!
Let's plug our x-value of 6 into each expression, evaluate our expression, and compare them using an inequality, which will be our answer.
9(4)-2(6)
36-12
24
2(9-6)
2(3)
6
As you can see, this gives us 24_6. As you can see, 24 is greater, so we will use the > inequality, giving us 24>6.
Therefore, our answer is B) >.
