Answer:
Dividing by 3 means splitting a number into 3 numbers, all equal. The division sign can be represented by a /.
For example, 12/3=4. We can check our answer by multiplying our answer by 3, and seeing if we get our original answer.
4*3=12
Division is the opposite of multiplication, so it makes sense that multiplication is a valuable tool to check our work.
Hope this helps!

Answer:
We conclude that 'A number t multiplied by -4 is at least −2/5' can be algebraically written as inequality such as:
Step-by-step explanation:
Given
A number t multiplied by -4 is at least −2/5
To determine
Write the sentence as an inequality.
For the inequalities, when we mention 'at least', we can term it as 'greater than or equal to' symbol such as '≥'.
It is stated that A number t multiplied by -4 is at least −2/5.
Let 't' be the number.
Multiplying t by -4 is: -4t
Thus, A number t multiplied by -4 is at least −2/5 will be written as:
-4t ≥ -2/5
Therefore, we conclude that 'A number t multiplied by -4 is at least −2/5' can be algebraically written as inequality such as:
