Question

In a certain town, the wind speed, x, in km/h on a certain day is described by two statements:
If 2 times the wind speed is increased by 2, the wind speed is still less than 46 km/h.
Twice the wind speed minus 27 is greater than 11 km/h.
Part A: Create a compound inequality to represent the wind speed range.
Part B: Can the wind speed in this town be 20 km/h? Justify your answer by solving the inequalities in Part A. Part C: The average wind speed in another town is 23 km/h but the actual wind speed is within 4 km/h of the average. Write and solve an inequality to find the range of wind speed

Answer 1

"If 2 times the wind speed is increased by 2, the wind speed is still less than 46 km/h."

2x+2 < 46

Answer 2

" Twice the wind speed minus 27 is greater than 11 km/h."

2x-27 > 11

Answer 3

2x+2 < 46 AND 2x-27 > 11

Answer 4

Part C:
something like this?
23-4< x < 23+4
