It’s D because the original is at +1 and it goes down to -1. If you count backwards starting at 1 to -1 you notice that it’s two digits apart

Plz help with this word problem
Fofino [41]
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

Svetlanka [38]

Answer:

z≤2

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−1/8z≥−0.25

Step 2: Multiply both sides by 8/(-1).

(8/−1)*(−18z)≥(8−1)*(−0.25)

z≤2
