Respuesta :

(-2.9a + 6.8) + (4.4a - 7.3)
= -2.9a + 6.8 + 4.4a - 7.3
Combine like terms. All "a" terms can only be added to other "a" terms, and all non variable terms can only be added to other non variable terms.
= 1.5a - 0.5

Final Answer: D. 1.5a - 0.5
The answer is d! You do 4.4a-2.9a and get 1.5a and then -7.3-2.9 and get -0.5
