Question

In a certain town, the inches of rainfall, x, on a certain day is described by two statements:

1.If 3 times the rainfall is increased by 2, the rainfall is still less than 26 inches.
2.5 plus twice the rainfall is greater than 11 inches.

Part A: Create a compound inequality to represent the rainfall range.

Part B: Can the rainfall in this town be 4 inches? Justify your answer by solving the inequalities in Part A.

Part C: The average rainfall in another town is 5 inches but the actual rainfall is within 4 inches of the average. Write and solve an inequality to find the range o

Answer 1

to find the range of rainfall in height in this town?
I need help with Part C.

Answer 2

5-4 < actual rainfall < 5+4

Answer 3

I know that it's going to be between 1 inch and 9 inches; I'm just confused on how to right the inequality.

Answer 4

*write

Answer 5

there are two parts to the inequality, the part where actual rainfall is 'less than' and the part where actual rain fall is 'more than' meaning we have the ineqaulity of
less than is: actual rainfall < 5+4
and
more than is: 5-4 < actual rainfall
being we have the same term in both 'actual rainfal' we can just smash the two together and get 5-4 < actual rainfall < 5+4
