b. melissa multiplied incorrectly. the correct answer is 9.5°f.

c. melissa added incorrectly. the correct answer is 4.5°f.

d. melissa added incorrectly. the correct answer is 5.5°f.

from 5 am to 10 am is 5 hours.

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
