(-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
440d=60t it would take jimmy 7.33 hours to get home if he drove at a constant rate of 60 Miles Per Hour
155/(2 1/2)=62
Sam drives at 62 m/h

Sam would drive 248 miles in 4 hours.
Hope this helps :)
