Answer 2

Answer:

3) 0.3937 x

Step-by-step explanation:

given that  one centimetre = 0.3937 inches

this can be express as 1 cm = 0.3937 inches

                            then 2 cm = 2(0.3937) inches

                                     3 cm = 3(0.3937) inches  

                                     4 cm = 4(0.3937) inches  and so on

like this if there are  x cm  

then it can be express as  x cm  = x ( 0.3937) inches  

                                            x cm =  0.3937 x inches
