Answer:
The correct answer is C
Step-by-step explanation:
If the number of bacteria

is a function only of temperature

, and the temperature

is a function only of time in hours

, then

If 35 cm represent the length of the plane which is 87.5 ft of the actual plane length. let 1 cm be x ft.
35 cm = 87.5 ft
1 cm = x ft
cross multiply this and the answer is 2.5 ft. Therefore, the scale drawing is 1 cm is 2.5 ft.
To correctly solve x from the given equation,
3x - 3 = 6x + 1
We first subtract 3x from both sides of the equation and this will give us,
-3 = (6x - 3x) + 1
Simplifying,
-3 = 3x + 1
Then, subtract 1 again from both sides of the equation to give,
-4 = 3x
Lastly, divide both sides by 3 giving us a final answer for x which is x = -4/3.
