Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 kilometres per hour and the other travels at an average speed of 70 kilometres per hour. How long after they leave the station will they be 50 km apart?

B. (12x + 6) ft
C (24x - 12) ft
D. (24x + 12) ft
If you can please show the steps
Answers
Answer:
C
Step-by-step explanation:
Remark
The easiest way to do this is to add the two givens together and then multiply by two. Why 2? Because the formula is P = 2(L + W)
Givens
L = 8x - 2
W = 4x - 4
Solution
P = 2*(8x - 2 + 4x - 4)
P = 2*(12x - 6)
P = 24x - 12

Answer:
1.The formula to convert Celsius to Fahrenheit is:
F = 1.8 C + 32
Multiply the Celsius temperature by 1.8.
Add 32 to this number.
Report the answer in degrees Fahrenheit.
Example: Convert 20°C to Fahrenheit.
F = 1.8 C + 32
F = 1.8 (20) + 32
1.8 x 20 = 36 so F = 36 + 32
36 + 32 = 68 so F = 68°F
20°C = 68°F

Identify the points which of the following coordinate pairs make the equation x - 9y = 12 true?
Show your reasoning.
1. ( 12, 0 )
2. ( 0, 12 )
3. ( 3, -1 )
4. ( 0, - 4/3 )
Answers
Answer:
Step-by-step explanation:
Because in equation x-9y=12
If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12
So, (12,0) make equation
(3,-1) also make equation
(3)-9(-1)=12
(0,-4/3) also make equation
Because
0-9(-4/3)=12
Only (0,12) is not making
Beacuse
(0)-9(12) is not equal to 12

Answers
Answer:
Well, -1-126 (-12b - 6 + 9b - 18) equals 378b + 2023.
Step-by-step explanation:
Subtract numbers:
−1−126 (−12−6+9−18)
−1−126 (−12−24+9)
Combine like terms:
−1−126 (−12−24+9)
−1−126 (−3−24)
Then you'll have to distribute:
−1−126 (−3−24)
−1+378 + 3024
