Answer:
y = 23/3
Step-by-step explanation:
Simplify both sides of equation
7 = y + -2/3
Flip equation
y + -2/3 = 7
Add 2/3 to both sides
y + -2/3 + 2/3 = 7 + 2/3
y = 23/3

I feel like it’s the last set but then again I haven’t done that kind of math in a few years. Hopefully that helps !
The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h
