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
Hi :)
To find the tan of a number, just type the number into your calculator and press 
.
, Rounded to the nearest hundredth, or 2 numbers after the decimal point, just like you asked

sry I just wanted the points I'm in middle school so I don't know this stuff either

it's blurry
Step-by-step explanation:
Answer:
No solutions: 6 - 3 + 4x + 1 =_4x + _2_
One solution: 6 - 3 + 4x + 1 = _3_x + _2_
Infinite many solutions: 6 - 3 + 4x + 1 = _4_x + _4_
Step-by-step explanation:
No solutions means it results in no x and a false statement like 3 = 0.
One solution means it results in x = a number.
Infinite solutions means its results in no x and in a true statement like 3=3.
- So to get No solutions: 6 - 3 + 4x + 1 =_4x + _2_
This will eliminate the x and result in 4 = 2 which is false.
- One solution: 6 - 3 + 4x + 1 = _3_x + _2_
This will result in x= -2
- Infinite many solutions: 6 - 3 + 4x + 1 = _4x + 4__
This will eliminate the x and result in 4 = 4 which is true.
