The distance flown by plane is 750 kilometers.
Step-by-step explanation:
Let,
Distance traveled by plane = x
Distance traveled by car = y
Total distance = x+y
According to given statement;
The distance by car was 125 kilometers less than the distance by plane.
y = x - 125 => x=y+125 Eqn 1
The total distance was 500 kilometers less than three times the distance traveled by car.
Total distance = 3y - 500
x+y=3y-500 Eqn 2
Putting value of x from Eqn 1;

Putting y=625 in Eqn 1

The distance flown by plane is 750 kilometers.

Answer:
12.81 miles
Step-by-step explanation:
You need to use the Pythagorean Theorem to draw a triangle.
10 squared + 8 squared = c squared.
100 + 64 = c squared
164 = c squared
find the square root of 164:
12.81.
Answer:
(x,y)=(5-2y,y), y belongs to all real numbers
Step-by-step explanation:
x=5-2y
3x=15-6y
3(5-2y)=15-6y
15-6y=15-6y
y∈All Real Numbers
(x,y)=(5-2y,y), y∈All Real Numbers
