In a certain town, the wind speed, x, in km/h on a certain day is described by two statements:1.If 2 times the wind speed is increased by 2, the wind speed is still less than 46 km/h.
2.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 in this town.

A) 1) 2x+2<46 2x<44 x<22 2) 2x-27>11 2x>38 x>19 therefore, the wind speed is in-between 19 and 22km/h (19>x>22). this was just making statements into equations. B) i don't know what a compound inequality is sorry :( C) i don't understand :( sorryyy
