8x + 4y = 20
4y = 20 - 8x
y = 5 - 2x
Hello, I am papaguy
Here is your answer
In terms of distance, the average speed for the total x miles you'd travel would be 50 miles per hour. However, if you include the fact that you spent less time traveling 60 miles per hour than 40, the average would be closer to 40 than 60 miles per hour.
Please note this is information you can use do not copy and paste.
Thank you papaguy And If I am wrong I will look into it!
A. 0.250006, 0.250007, 0.250008

Answer:
Step-by-step explanation:
The opposite of a number is found by taking the opposite sign of the one given. The opposite of 3 is -3; the opposite of -2 is 2.
Therefore, the opposite of -5.5 (point P) is 5.5 (point S).
Answer:
Step-by-step explanation:
Let the speed of the car be "X". From 3 am until 1 pm (10 hours), the car will travel 10*X miles.
The speed of the airplane is (X +200). From 11 am until 1 pm (2 hours), the plane will travel 2*(X+200).
The distance travelled is the same, so:
10*X = 2*(x+200)= 2x+400
Subtract 2*X from both sides:
8*X = 400
X = 400/8 = 50 mph.
