Step-by-step explanation:

Combine like terms

6) -4f - 9 -f + 15 = -4f - f -9 +15

= -5f + 6

7) 1.5g - 10 + 6.5g - 3 = 1.5g + 6.5g - 10 - 3

= 8.0g -13

= 8g - 13

$\frac{1}{2}h + 2h + \frac{3}{2}h - 1 = \frac{1}{2}h+\frac{3}{2}h+2h - 1\\$

$= \frac{1+3}{2}h + 2h -1\\\\= \frac{4}{2}h + 2h -1\\\\= 2h + 2h -1 \\\\= 4h - 1$

9) 4.2j + 6.7j - 5j - 5 = 10.9j - 5j - 5

= 5.9j - 5
