Answer:
This statement is "TRUE".
Step-by-step explanation:
Every elementary row operation is reversible. You can get the reverse answer by multiplying by a constant or by multiplying by its inverse. You can add one row to another row and subtract row 1 from row 2 to get it back.
There would probably be multiple ways to solve this, but I will only show you one of them.
First, we need to figure out how many tablespoons of the chemical solution it takes to decrease the number of bacteria in a gallon to 300. So we subtract 1200 by 300, to find the number of unnecessary bacteria, which is 900. Now we divide 900 by 75, which is 12. So it would take 12 tablespoons of the chemical solution to make a gallon have 300 bacteria.
There are 500 gallons, and we need to put 12 tablespoons of the chem-solution in each gallon. So we multiply 500 by 12, which is 6,000. Meaning that 6,000 tablespoons of chemical solution would be needed to make the 500-gallon tank have 300 bacteria per gallon.
Answer: What question?
Step-by-step explanation:
Answer;
-Translation
Explanation;
-Any image in a plane could be altered by using different operations, or transformations. Translation is when we slide a figure in any direction.
-Translation involves sliding a figure in any direction without changing its size, shape or orientation.Translations are often referred to as slides. You can describe a translation using words like "moved up 3 and over 5 to the left" or with notation.
