Alexandra has 78 emails in her inbox. she deletes 47 emails. how many emails are left in her inbox? draw jumps and label the number line to show your thinking.

This problem can be solved directly by subtraction.

We are given that there are initially 78 emails in her inbox.

We take out or delete 47 emails therefore we subtract 47 from 78, hence:

                78 – 47 = 31

So there are 31 emails left in her inbox.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
