Yeah, these are tough.
When the plane is flying in the same direction as the wind,
the wind helps it cover ground faster.
Plane + Wind = 460 mph
When the plane is flying opposite to the wind, the wind makes it
cover ground slower.
Plane - Wind = 400 mph
================================
OK. So far we have
Plane + Wind = 460 mph
Plane - Wind = 400 mph
Add the two equations, and you get
2 Plane + zero = 860 mph
Divide each side by 2: Plane = 430 mph
Plug that into the first equation: 430mph + Wind = 460 mph
Subtract 430 mph from each side: Wind = 30 mph
11/8 or 1 3/8
You must have the same denominator. Therefore, multiply 1/2 by 4 to get a denominator of 8. Be sure to do this for the numerator as well. You end up with 4/8 plus 7/8. You result with 11/8 or simplified 1 3/8.
Answer:
y =4/5x + 3
Step-by-step explanation:
−4x−6=−5y+9
Step 1: Flip the equation.
−5y+9=−4x−6
Step 2: Add -9 to both sides.
−5y+9+−9=−4x−6+−9
−5y=−4x−15
Step 3: Divide both sides by -5.
−5y/−5
=
−4x−15/−5
y=
