Quora Open This sounds like a multiple-choice test question from a standardized test. But let's take a look at it. If 15bx – 20 > 35 ,where b is a positive constant ... So you are given an equation here. Next you are given something to compare it to. 4 – 3bx. So we want to go from 15bx – 20 to 4 – 3bx. The point is for you to think about the relationship. What is the relationship of -20 to 4? How would you turn -20 into 4? By dividing by -5. Of course, division by a negative means you have to reverse the direction of the inequality. 15bx – 20 > 35 15bx – 20 35 -5 -5 4 – 3bx < -7. Note. You will be given an option with the incorrect inequality! After all, they want to see whether you remember every part of handling an inequality like this. Notice that we didn't have to solve for x. We didn't have to do a lot to the equation. We just had to do enough. That's why it is important to take your time to read the problem carefully and think about what it wants.

To calculate the time taken for the machine to fill 825 containers of oatmeal, we use the formula below.
Formula:
- R = C/t.................. Equation 1
Where:
- R = Number container filled by the machine in one minute.
- C = Total number of containers
- t = time taken the container
Make t the subject of the equation
- t = C/R............... Equation 2
From the question,
Given:
- C = 825 container of oatmeal
- R = 50 containers of oatmeal per minute
Substitute the values above into equation 2
- t = 825/50
- t = 16.5 minutes.
Hence, the time taken for the machine to fill 825 containers is 16.5 minutes.
