The question is not defined very well so if u would repeat it
Answer:
45 rows will need to be built to hold 1350 cars. (for 30 spaces a row)
19 fewer rows are needed if the rows fit 50 cars (for the 50 spaces a row)
Step-by-step explanation:
for the first question divide 1350 by 30 and the second divide 1350 by 50, good luck!
-5.4v+0.3v= -5.1v
Because both numbers have a common variable of 'v,' they can be combined.
