Answer:
100 not so good seats
50 good seats
Step-by-step explanation:
Let x represent good seats and y represent not so good seats
[i] 3x + 2y = 350
[ii] x+y = 150
[iii] y = 150 - x
substitute this to equation [i]
3x + 2y = .350
3x + 2 (150-x ) = 350
3x + 300 - 2x = 350
3x-2x = 350 - 300
x = 50 good seats
now substitute what you got to equation [iii]
y = 150 - 50 = 100 not so good seats
when we check the answer by using equation [i] we find that it is correct:
3x + 2y = 350
3(50) + 2(100) = 350
150 + 200 = 350
350 = 350

Answer:
in this for 8 times 7 is 56 and 42 is for 6 times 7
Step-by-step explanation:
there are 7 days as one week so every 8 days would be 1 week and an extra day while six days is almost a week so every 6 days times 7 is 42 while 8 times 7 is 56 than subtract how much of the total number eight days is faster and that 56 for 8 days and 42 for six 56-42=14
