#21 & #22 need to be correct and i'm not sure how to solve them.

#21: 44 divided by 2 equals 22
22+6"28
#22: 4.90+3.90•3+1.95=18.55

#21. The equation is x + x + 6 = 44
Then                                    - 6    -6
                                
                                             2x = 38
Then divide each side 2       
                                             2       2

 So you get x = 19
So one ribbon is 19 the other one is 25 because 19 + 6 = 25
