Answer:
y=1
Step-by-step explanation
the x is like a imaginary 1 so 4*x=4-3=1
Answer:
I think its 2 good luck

Step-by-step explanation:
The steps in the question isn't clear enough, however the question is answerable.
From the question, we understand that one model shows that:
200 is 10 times 20
While the second model shows that
200 is 10 times 2
The first model that says
200 = 10 times 20 makes sense.
This is so, because 200 = 20 * 100
While the other model which says
200 = 10 * 2 is nonsense.
This is so because, 200 ≠ 10 * 2
To solve the problem we will use this equation where,
d will be distance.
x is the speed of the plane without tailwind.
y is the speed of the wind affecting the plane.
Going to Philadelphia the speed of the plane affected by wind will be x-y=220 miles/hr
Coming back with a tailwind, the speed of the plane will be x+y= 280 miles/hr.
since time = distance / speed, t1 =d/220 and t2 = d/280
and since the total time traveled is 6.5hrs
d/220 + d/ 280 = 6.5hrs
d = 800.8 miles x 2 (back and forth trip) the answer is 1601.6 miles
48/5
9x5+3 divide by 5
45+3 divide by 5
48/5
