1.  3.5w + 24.5

2. 1/2f + 5

3. 12z + 8

4. 20b + 16c

5. 30d + 18

6.  24 - 8h

4,5 and 6 cannot be simplified. 
1. 3.5(w+7)= 3.5w + 24.5

2.1/2(f+10)= 1/2f + 5

3.4(3z+2)= 12z + 8

4. 20b+16c= you cannot add two different variables

5. 30d+18= already simplified

6. 24g-8h= again, you cannot add/subtract two different variables
