Question

Missy is getting married and addressing invitations. She has at least 140 envelopes and has addressed 26 of them. Write an inequality that describes how many more invitations must be addressed.

Answer 1

To solve this, you must find out the total amount of envelopes she has, and the number of envelopes she has already mailed out. One equation that can work is:
140≥26+x or 140=26+x
X represents how many more envelopes she must mail out still
And you must use the ≥ or = symbol because 140 is the total amount of envelopes she has. She doesn’t have more than 140, 26+x must be equivalent to 140, or 140 must be greater or equal to 26+x.
Hopefully this made sense : )
