Let #r# equal the amount of rain.

We can then write an inequality as:

#r >= 3#

Answer 2 · 2018-02-13T22:22:59

You would use #ge#

You want to make sure that you use a 'greater than or equal to' inequality to match the meaning of 'at least'.

Rain #ge# 3 inches

#x>=3#

Convert the words into an inequality with #x# being inches of rain:

#overbrace("At least")^(x>=)# #overbrace(3 "inches")^3#

#x>=3#

Have a nice day!

#x ≥ 3#

Let #x# represent inches of rain. Since it says "at least", we know #3# is the smallest value it can be. This means your answer is

#x ≥ 3#

since #x# can be #3# but can't be any lower than that.
