Answer:

z ≤ 8/21

​

Step-by-step explanation:

Flip the inequality sign since you are multiplying by a negative number

 21z-8  ≤ 0

1.2    Divide both sides by  21  

 z-(8/21)  ≤ 0

Add  8/21  to both sides

z ≤ 8/21

Whats the answer to 1/5x=121 x=?
weqwewe [10]
You have an algebraic expression in which you are solving for x.  When you are solving for a variable, you need to isolate it all alone.  Since you are multiplying by 1/5, you will have to undo it by multiplying by its reciprocal.  In this case you are multiplying both sides by 5/1.

5/1 *1/5x = 121*5/1
x = 605

To check your answer, plug this value in for x and multiply it by 1/5.  You should arrive at 121!  Good luck!
