B. 0.25 + 1.00

C.0.25 + 4.50

D.0.25 -3.00


I would love an explanation to help me understand how to solve the other problems like this one

Answer 1

it is A. 0.25x - 6.50

You use distributed property first so the equation will be 3x - 1 - 2.75x - 5.50

Then you combine like terms so 3x - 2.75 will equal 0.25x

The subtraction symbol will stick with 1 making it -1 so the second part will be -1 - 5.50 will equal 6.50

And finally, the expression will be 0.25x - 6.50

Answer 2

I think is B but I’m not sure
