Step-by-step explanation:
2x + 1 = 16
2x = 15 (subtract 1 on both sides)
x = 7.5 (divide 2 om both sides)
Since 7.5 is not an integer, (a) is No.
However 7.5 is rational, therefore (b) is Yes.

Answer:
They could cover 90 kilometres in 6 hours, after the terrain changed.
Step-by-step explanation:
Their speed, when they were traversing through the marsh, is:
speed = distance/time
s = 20 km / 4hr
s = 5 kmph
If their speed tripled, then it will be: 5*3 = 15 kmph
distance = speed * time
d = 15 km/h * 6h
d = 90 km
They could cover 90 kilometres in 6 hours, after the terrain changed.
Answer: The driver has $95.25 after the last ride.
Step-by-step explanation: First we need to know how much money he recieved from each ride. Multiply 3.5 with each number.
$3.5 x 10 = $35
$3.5 x 5.5 = $19.25
$3.5 x 19 = $91
Now add them up.
$35 + $19.25 + $91 = $145.25.
However, he spends $50 on gas. So subtract $145.25 and $91.
$145.25 - $91 = $95.25.
Therefore, the driver has $95.25 after the last ride.
